WordPress Maintenance: 7 Things That Go Wrong

The short answer: a WordPress website is not a “build it once and forget it” project. Plugins, themes, WordPress itself, the PHP software your host runs, and your security certificate all change on their own schedule. Regular WordPress maintenance (updates, off-site backups, security checks and uptime monitoring) is what keeps a small-business site safe, fast and online. Skipping it is how sites get hacked, break after an update, or disappear with no way to restore them.

If you own a small business, your website is probably your hardest-working employee. It answers questions at 2 a.m., books appointments, and sends people to your door. But like any employee, it needs a little care to keep doing its job. Here’s why WordPress maintenance matters, with real examples of what goes wrong when nobody is watching.

What is WordPress maintenance?

WordPress maintenance is the routine work that keeps a WordPress website secure, working and recoverable. For most small-business sites it includes:

Updates to WordPress core, plugins and your theme, tested so they don’t break anything.
Backups taken automatically and stored somewhere other than your web host, so you can restore the site if something goes wrong.
Security monitoring for malware, suspicious logins and known plugin vulnerabilities.
Uptime monitoring so someone knows within minutes if your site goes down.
Server health checks, like keeping PHP up to date and making sure your SSL certificate renews.
Small fixes and content changes, like swapping a photo, updating hours or fixing a broken form.

Why WordPress sites need ongoing care

WordPress powers a huge share of the web, and that’s a good thing: it’s flexible, affordable and well supported. The flip side is that a typical site is built from many moving parts made by different people. Your site might run WordPress itself, a theme, a page builder like Elementor, a contact form plugin, an SEO plugin, a caching plugin and a few more. Each one gets updates, and each one can have security holes.

The numbers show how fast this moves. Security firm Patchstack counted 7,966 new vulnerabilities in the WordPress ecosystem in 2024, about 22 every day. 96% of them were in plugins, 4% were in themes, and only seven were found in WordPress core. A third of those vulnerabilities had no fix available when they were made public (Patchstack, State of WordPress Security in 2025).

In other words, WordPress itself is solid. The risk lives in the add-ons, and that risk changes every week.

7 real examples of what can go wrong

These aren’t scare stories. Each one happened to real websites, and each one is the kind of problem regular maintenance is designed to catch.

1. A popular plugin hands attackers the keys

In August 2024, researchers found a critical flaw in LiteSpeed Cache, a speed plugin installed on more than 5 million WordPress sites. It let an attacker who wasn’t logged in make themselves an administrator and take over the site. A fix came out in version 6.4 on August 13, 2024, but at the time only about a quarter of sites had installed the latest version, leaving an estimated 3.8 million sites exposed (CyberInsider).

The lesson: the fix existed. The sites that got hurt were the ones where nobody clicked “update.”

2. A security plugin becomes the security problem

In November 2024, a flaw was found in Really Simple Security (formerly Really Simple SSL), a plugin used on more than 4 million sites. Rated 9.8 out of 10 for severity, it let attackers log in as any user, including an administrator, on sites that had its two-factor login feature turned on (The Hacker News). The plugin’s makers worked with WordPress.org to push the fix out automatically, which helped, but not every site accepts automatic updates.

The lesson: even plugins you install for security need watching. Someone should know what’s on your site and react the same day a serious flaw is announced, because Patchstack notes attacks often start within hours of a vulnerability going public.

3. Your hosting company gets breached

In November 2021, GoDaddy disclosed that an attacker had been inside its Managed WordPress hosting system since September 6, 2021, using a compromised password. Up to 1.2 million customers were affected. Exposed data included email addresses, the original WordPress admin passwords set when sites were created, sFTP and database usernames and passwords, and, for some customers, SSL private keys (The Hacker News).

The lesson: this isn’t a knock on any one host. Big hosts are big targets. Your site is safer when someone changes default passwords, uses strong unique logins, keeps an eye out for the host’s security notices, and keeps backups that don’t depend on the host alone.

4. An update breaks the site

Updates are essential, but they aren’t risk-free. When WordPress 5.5 came out in August 2020, it removed an older piece of code called jQuery Migrate. Many themes and plugins still relied on it, so sites suddenly had broken menus, sliders and editors, and some owners couldn’t edit their content at all. A temporary helper plugin passed 10,000 installs within a week as site owners scrambled for a fix (WP Tavern).

The lesson: “just turn on auto-updates” isn’t a full plan. Good maintenance means taking a backup first, testing bigger updates on a staging copy, checking the site afterward, and rolling back fast if something breaks.

5. The backups are gone too

In March 2021, a fire destroyed a data center run by European host OVHcloud in Strasbourg, France. About 3.6 million websites went offline (Netcraft). Some customers who paid for backups found out the hard way that their backups were in the same building as their sites. A French court later ordered OVHcloud to pay damages in two of those cases (Blocks and Files).

The lesson: a backup only counts if it’s stored somewhere else and you’ve actually tested restoring it. Keep at least one copy off your host, on a schedule, and check that it works.

6. Your site runs on outdated PHP

PHP is the programming language WordPress runs on, and your host lets you pick the version. Each PHP version gets two years of active support and then two years of security fixes only. After that, no more security patches. PHP 8.1 and everything older no longer get any fixes, and PHP 8.2 stops getting security fixes on December 31, 2026 (PHP.net supported versions).

Plenty of small-business sites are still running old PHP because “it works.” The catch is that newer plugin versions often need newer PHP, so an outdated server can block the very security updates you need. Moving up isn’t always a one-click job either, since older plugins may not work on newer PHP, so it should be tested first.

The lesson: check your PHP version a couple of times a year and plan upgrades before support ends, not after.

7. Your SSL certificate expires

Your SSL certificate is what puts the padlock in the browser and the “https” in your web address. When it expires, visitors get a full-page warning that your site is “not secure,” and most of them leave. Online checkouts and forms can stop working too.

This is about to come up more often. The CA/Browser Forum, the group that sets the rules for certificates, voted in 2025 to shorten how long certificates can last: a 200-day maximum starting March 15, 2026, 100 days starting March 15, 2027, and just 47 days starting March 15, 2029 (CyberInsider).

The lesson: more renewals mean more chances for one to fail quietly. Auto-renewal plus monitoring that alerts someone before a certificate expires is the safe setup.

What does skipping maintenance really cost?

The cost of a neglected site rarely shows up as one big bill. It shows up as:

Lost customers who hit a broken page or a security warning and go to a competitor instead.
Emergency cleanup after a hack, which almost always costs more than prevention would have.
Search ranking damage if Google flags your site as hacked or it’s down when Google visits.
A full rebuild when there’s no clean backup to restore from.
Your time, spent on hold with your host or searching error messages instead of running your business.

A simple WordPress maintenance checklist

Whether you do it yourself or hire someone, here’s a solid baseline for a small-business site:

Every week

Take a backup before updating, then update plugins, themes and WordPress core.
Check the site after updates: home page, contact forms, checkout and menus.
Review security alerts for any plugins you use.

Every month

Confirm automatic backups are running and stored off your host.
Run a malware scan and review admin user accounts.
Delete plugins and themes you no longer use.
Check site speed and fix anything that has slowed down.

Every quarter

Test restoring a backup to make sure it actually works.
Check your PHP version against the supported list.
Check your SSL certificate’s expiration date and auto-renewal.
Update passwords for admin, hosting, sFTP and database accounts.

Should you do it yourself or hire help?

If you’re comfortable with WordPress and you’ll actually block out the time, you can handle a lot of this yourself. Where most busy owners get stuck is consistency: updates pile up, backups are never tested, and a problem gets noticed only when a customer calls to say the site is down.

Hiring a maintenance partner makes sense when your website brings in leads or sales, when you don’t have time to check it every week, or when you’d rather not be the one figuring out what broke at 9 p.m. on a Friday.

Frequently asked questions

How often should a WordPress site be updated?

Check for updates at least weekly. Apply security fixes as soon as they’re released, especially for plugins with a known vulnerability, and take a backup before any update.

Is it safe to turn on WordPress auto-updates?

Auto-updates are helpful for minor security releases, but they aren’t a complete plan. Without backups and someone checking the site afterward, an automatic update can break a page or form and nobody notices until a customer does.

Doesn’t my web host already handle maintenance?

Most hosts, including managed WordPress hosts, keep the server running and may update WordPress core. They usually don’t test your plugins and theme, fix conflicts, or check that your forms and checkout still work. Host backups are also often stored with the host, which is why an independent off-site copy matters.

What happens if my WordPress site gets hacked?

A hacked site may show spam, redirect visitors to other sites, send junk email, or get flagged by Google and browsers. Cleanup means removing the malware, closing the hole that let it in, changing every password and asking Google to review the site. A clean, recent backup makes recovery much faster.

How much does WordPress maintenance cost?

For small-business sites, ongoing maintenance typically runs from around $100 to a few hundred dollars a month, depending on how much hands-on work is included and whether the site is an online store. Trevi Web Co. plans start at $99 a month.
