WordPress maintenance can be easy to put off when your website seems to be working. But behind the scenes, outdated software, untested backups and neglected plugins can create security risks or cause problems for your customers.
That matters right now. WordPress released version 7.1.4 on 28 October 2026 to fix multiple security issues, and WordPress recommends updating sites immediately. One fix addresses a weakness in the upgrade process that could allow remote code execution during the upgrade window.
Here are seven common WordPress website maintenance mistakes, and practical ways to put them right.
1. Putting off security updates
An update notification can feel like one more task on a busy to-do list. But delaying a security release leaves your website exposed to problems that may already be publicly known.
If your site is running an older version, check your WordPress dashboard and arrange the update promptly. Some websites can install minor and security updates automatically, but you should still check that the update completed successfully. Don’t assume the notification has taken care of everything.
How to fix it: Set a routine for reviewing updates, and prioritise security releases. If your site is business-critical or the update process is unfamiliar, ask a developer to handle it safely.
2. Updating without a reliable backup
Updates are important, but they can sometimes conflict with your theme, plugins or hosting setup. A backup gives you a way back if something goes wrong.
A backup is only useful if it is recent, complete and restorable. Saving files without a copy of the database, for example, may not be enough to bring the whole site back as it was.
How to fix it: Before significant updates, make sure you have a recent copy of both your website files and database. Check where backups are stored and how you would restore them. For important websites, make recovery part of your maintenance routine rather than leaving it until an emergency.
3. Updating WordPress core but forgetting plugins and themes
WordPress 7.1.4 addresses issues in WordPress itself. It does not automatically update every plugin or theme installed on your website. Those components have their own release schedules, security fixes and compatibility requirements.
An old plugin can still present a risk, even when WordPress core is up to date. Equally, keeping plugins you no longer use adds unnecessary software to manage.
How to fix it: Review your plugins and themes as well as WordPress core. Update the tools you actively need, check the developer’s notes if an update is significant, and remove anything you no longer use. Avoid installing a plugin simply because it promises a quick fix; choose maintained tools that are right for your site.
4. Updating everything on a live site without checking first
Clicking every update button at once can save a few minutes, but it can make it harder to identify the cause of a problem if something breaks. A plugin update may not work smoothly with your theme or another plugin, particularly on a complex site.
For smaller websites, careful updates may be straightforward. For sites that take enquiries, process payments or support daily operations, a little more planning can prevent disruption.
How to fix it: Where possible, test significant changes on a staging copy of your website before applying them to the live site. Update in a controlled order, check for compatibility notes, and keep a record of what changed. If staging is not available, choose a quiet time and have a backup and rollback plan ready.
5. Assuming an update worked because the homepage loads
A homepage that appears normal doesn’t prove every important part of your website is working. A contact form could stop sending messages, a booking function might fail, or a checkout could develop a problem that only appears when a customer uses it.
How to fix it: After updates, check the tasks that matter to your business. For example:
- Submit a test through your main contact form.
- Check key pages on a mobile phone and desktop.
- Test logins, bookings or payments where relevant.
- Look for broken layouts, error messages or missing images.
- Confirm that important notifications arrive in the right inbox.
Make these checks part of the process, not a step you skip when the update finishes.
6. Treating WordPress updates as the whole maintenance job
WordPress website maintenance is about more than pressing “Update”. Your hosting environment, SSL certificate, site performance, monitoring and backups all contribute to a dependable website. If something goes wrong at server level, updating a plugin alone won’t solve it.
For growing businesses, downtime can mean missed enquiries and frustrated customers. A website also needs to keep performing well as your content, traffic and business needs change.
How to fix it: Include hosting health, site monitoring, SSL renewal and performance in your maintenance checks. WordPress’s guide to updating your website also recommends backing up before an update and checking your site afterwards. Your maintenance routine should cover the full setup that keeps the website online, not just the dashboard.
7. Waiting for something to break before you act
Reactive maintenance can turn a small issue into an urgent one. If no one knows who owns the website, when it was last backed up or how quickly updates are reviewed, important tasks can be missed.
That is especially common when a website was built some time ago, the original developer is no longer involved, or several people share responsibility without a clear plan.
How to fix it: Create a simple maintenance schedule and make ownership clear. Record when backups are taken, who checks updates, how problems are reported and what needs testing after a change. A regular review also gives you the chance to spot outdated content, slow pages or issues affecting your customers.
