A PrestaShop store does not always fail abruptly. Most of the time issues start before the visible outage: an unusable backup, unnoticed errors in logs, an obsolete module, slower pages or transactional emails that stop sending.
The common blocker is simple: you mix monthly maintenance, weekly checks and precautions to take before an update. As a result, basic checks get postponed.
This PrestaShop maintenance checklist gives you an actionable routine for a store already in production. You will know what to check, how often, and when a check should become a proper intervention.
Start with a simple routine: weekly, monthly and before any update
The most common request on this topic is practical: a routine to run for an online store. The simplest approach is to separate three moments: the weekly check, the monthly review and the actions to take before a technical change. As of 3 November 2026, PrestaShop maintenance mode is located at Shop Parameters > General > Maintenance.
What to check every week without touching the code
The weekly check ensures the shop is functioning normally.
- Front office accessible: open the homepage, a product page and the basket.
- Back office accessible: verify you can log in and the admin remains usable.
- Recent orders: confirm recent orders have been created and their statuses are coherent.
- Business-facing emails: check a key email has been received in a monitored inbox.
What to verify each month on a live store
The monthly review covers sensitive areas of a production shop.
- Backups: presence of a full copy of files and database, stored outside any public location.
- Logs: read hosting and PrestaShop logs to spot recurring errors.
- Updates: inventory of core, theme and modules to handle.
- Performance: check key pages, added scripts and the images folder.
- Technical SEO: check actual indexing and any URLs returning errors.
- Orders and emails: validate the full flow up to the email sent.
What to do additionally before updating the core, a module or the theme
Before any modification, PrestaShop recommends backing up files and the database. To keep diagnostics clear:
- Note the starting point: versions involved and the objective of the change.
- Prepare rollback: ensure the day's backup is complete.
- Isolate the change: update one item at a time, especially modules.
- Frame the intervention: enable maintenance mode if you work in production.
- Test immediately afterwards: front office, back office, basket, payment, emails.
- Before adding or replacing a module: take the time to spot a risky PrestaShop module before installing it.
Check backups, logs and first warning signs first
The first level of maintenance is not updates. It is the ability to restore the shop and to spot a drift before it becomes visible to customers.
A useful backup is complete and not exposed
PrestaShop recommends backing up both files and the database, and advises against leaving backups in the shop root or any publicly exposed location. The official documentation on PrestaShop backups makes this clear.
- To check monthly: presence of a complete copy of files, database and modules.
- Simple check: confirm the backup is not empty and not stored in a public folder.
- Alert point: if you cannot restore it, it is not yet reliable.
Logs to review every month
PrestaShop advises regularly consulting hosting error logs and the shop's logs. Recurring errors often appear there before they are seen by customers.
- Where to look: hosting error logs and logs available in PrestaShop.
- What to look for: recurring errors, messages tied to a specific module or anomalies repeating across several days.
- When to act: if the same error affects payment, checkout, back office or emails, it should be fixed before the next update.
Simple checks that prevent a hard outage
A hard outage is often preceded by subtle signals: unstable back office access, repeated errors, slower pages or emails that stop sending.
- Put under watch: accessibility of front and back office, repeated errors, email anomalies.
- Classify: simple observation, routine clean-up or technical fix.
- To complement this routine: revisit the checks that help anticipate a PrestaShop outage.
Frame updates and security points in production
Monthly maintenance is not about applying every available update. The aim is to reduce risk. For modules and themes, PrestaShop recommends regular updates, updating modules one by one and removing obsolete modules.
Update core, modules and theme in the right order
On a production shop, start with an inventory then isolate each change.
- List: core, theme and modules involved.
- Handle one item at a time: PrestaShop recommends updating modules one by one to more easily find the source of any issue.
- Test between each step: navigation, basket, payment, order creation, confirmation email.
- Avoid bulk updates: they complicate diagnosis.
Remove obsolete modules and limit override risks
An obsolete or unused module increases risk. PrestaShop recommends removing them and reminds that overrides should be avoided when hooks can suffice.
- Monthly check: list installed modules that are unused or obsolete.
- Sensitive point: check whether critical behaviours rely on old overrides.
- If scope becomes complex: lean on occasional or monthly PrestaShop support to manage sensitive updates.
Switch to maintenance before intervention and validate the result
Maintenance mode protects the customer experience during an intervention. As of 3 November 2026, its documented location is Shop Parameters > General > Maintenance.
- Simple check: confirm you know how to enable it and retain your own access.
- If you have a preproduction: validate updates there first.
- After the intervention: test front office, back office, basket, payment and emails immediately.
Check the store's real performance every month
A shop can remain accessible while degrading on key pages. The monthly review must therefore look at real performance, not only whether a page opens.
What to look at for server, third-party scripts and the images folder
PrestaShop recommends monitoring server load, added scripts and the size of the images folder, and cites Google PageSpeed as a control tool.
- Measure each month: homepage, category, product page, basket and most visited pages.
- Watch: recently added third-party scripts, pages that slow down, images folder growing unchecked.
- To put the diagnosis in order: revisit the most frequent technical causes of a slow PrestaShop site.
When to clean the database and what to prioritise
PrestaShop recommends regularly cleaning logs, abandoned carts and orphan tables. It's routine housekeeping useful to avoid accumulation.
- To check each month: volume of tables related to logs, abandoned data and remnants of old modules.
- Simple check: spot tables that grow without a clear business reason.
- Routine cleaning: purge obsolete data as defined by your procedure.
How to track Core Web Vitals without overinterpreting one test
On 7 May 2025, web.dev defined Core Web Vitals thresholds as: LCP ≤ 2.5 s, INP ≤ 200 ms and CLS ≤ 0.1. Overall classification of a page or site relies on the 75th percentile of visits.
- What it changes: a single good test is not enough.
- Monthly check: compare trends on your strategic pages rather than an isolated score.
- When to intervene: if sales pages remain persistently outside thresholds, first look for the main lever to act on.
Cover technical SEO, orders and emails every month
A shop can stay online while having unindexed URLs, a broken funnel or missing emails. This area should therefore be part of the monthly routine, not only incident response.
Search Console checks that reveal real indexing problems
As of 3 November 2026, Google recommends using the Page Indexing and Crawl Stats reports in Search Console to spot inaccessible URLs, as explained in Google Search Central's technical documentation.
- To check each month: rise in non-indexed URLs, URLs accessible to users but not to Googlebot, abnormal crawl variations.
- Keep in mind: a sitemap helps Google discover your URLs but does not guarantee indexing or ranking.
- Control point: also monitor the www and non-www variants.
Technical SEO errors to spot quickly
The most costly errors are often simple: an error page responding 200, an untracked site variant or broken URLs after a change.
- Soft 404: if a page is truly gone, it should respond 404 or 410, not return a 200 with an error message.
- Simple check: spot URL patterns that fail after an update or module deactivation.
- Check after changes: categories, product pages, CMS pages and pagination if they are part of your tracked pages.
The essential business check: orders created, statuses coherent, confirmations sent
In the PrestaShop order cycle, an email with order details is sent after successful order creation. As of 3 November 2026, email settings are documented in the back office at Configure > Advanced Parameters > E-mail. The shop chooses between an SMTP connection and PHP mail.
- To check each month: order actually created, correct status, confirmation email received, no visible payment anomalies.
- Where to check: recent orders, a test inbox, email configuration and visible returns from the payment module.
- When to start diagnostics: if payment appears to go through but the order is not created, or if the order exists without an email.
- Useful starting point: revisit the first checks when a PrestaShop payment module stops working.
Turn this checklist into a followed monthly routine
A checklist is only useful if it is the same month after month and each check leaves a trace. The simplest is a short format, always in the same order, with a clear result at the end.
Create a shared checklist with date, owner and result
Your monthly document can fit on one page. It should answer three questions: what was checked, where it was checked, and what was observed?
- Check date
- Owner
- Block checked: backups, logs, updates, performance, SEO, orders, emails
- Result: OK, monitor, incident
- Evidence: screenshot, export, log name, email received, order verified
- Planned action: nothing, clean-up, technical intervention
Distinguish validated check, anomaly to watch and incident to fix
You will save time if each point ends in exactly one of these three boxes.
- Validated check: backup present, recent orders coherent, emails arriving.
- Anomaly to watch: increase in slowness on some pages, isolated errors in logs, drop in crawl for some URLs.
- Incident to fix: order not created, confirmation email missing, recurring payment errors, important URLs inaccessible.
When to move from an internal routine to structured maintenance
If the monthly review is postponed, if anomalies recur month after month or if technical changes pile up, an internal routine is no longer enough. Keep the same order of checks each month, then escalate quickly anything that affects sales, indexing or emails.
If you want to structure this routine or take over a shop without a clear history, I offer monthly maintenance for a PrestaShop store. Diagnosis is free and I reply within 24 hours.
Frequently asked questions
What should I check every month on a PrestaShop store to avoid outages?
Each month, check at least file and database backups, hosting and PrestaShop logs, updates to schedule, obsolete modules, performance of key pages, indexing in Search Console, and the full flow of order, payment and confirmation email. The goal is to detect drifts before they become visible to customers.
What is the difference between an existing backup and a truly tested backup?
An existing backup is simply a copy stored somewhere. A truly tested backup is one where you have verified the contents, storage and ability to restore. If you have the copy but no restoration procedure, you do not yet have a reliable backup for a real incident.
Can I update PrestaShop and its modules directly in production?
It is technically possible, but not the safest method. PrestaShop recommends backing up before any change, using maintenance mode during the intervention and updating modules one by one. If you update in production, limit the scope and test immediately afterwards on front office, back office, basket and emails.
Which performance elements should I check each month on PrestaShop?
Check speed on key pages, size of the images folder, newly added third-party scripts, server load signs and accumulation of obsolete data in the database. PrestaShop also recommends regular cleaning of logs, abandoned carts and orphan tables. For Core Web Vitals, focus on the overall trend rather than a single score.
Which technical SEO checks should I run each month in Search Console for a PrestaShop store?
Review the Page Indexing and Crawl Stats reports monthly to spot inaccessible URLs, crawl variations or pages leaving the index. Also check www and non-www variants, soft 404s and truly deleted pages. A sitemap helps Google discover URLs but does not guarantee indexing.
How do I verify that transactional emails and order confirmations are still sending correctly?
The simplest method is to check a recent order or a test scenario: the order must be created, receive the correct status and trigger the expected email. If the order exists without an email, or payment seems accepted without order creation, check email configuration, visible returns from the payment module and the logs.
