Running a WordPress website offers flexibility, customization, and scalability, but it also comes with its share of technical challenges.

Understanding common WordPress errors—and how to fix them—helps you maintain a stable, secure, and high-performing site.

This guest post explores the most frequent WordPress errors, what causes them, and how you can solve them efficiently without diving into complex troubleshooting. With the right strategies and the support of a Virtual oplossing expert WordPress development service, you can keep your website running smoothly and minimize downtime.

1. The White Screen of Death (WSoD)

One of the most frustrating issues for WordPress users is the White Screen of Death. In this scenario, your screen loads entirely white, with no error messages or clues to identify the problem.

What Causes It?

  • Plugin conflicts

  • Theme malfunction

  • Memory limit exhaustion

  • Core file issues

How to Fix It

Start by deactivating all plugins to identify whether one of them is the cause. If the site loads normally afterward, reactivate plugins one by one until the faulty one is found. Another approach is switching to a default theme like Twenty Twenty-Four to check for theme-related errors. Increasing the memory limit can also help when the issue is related to resource exhaustion.

A professional team specializing in Virtual oplossing expert WordPress development service can diagnose and resolve these errors quickly, ensuring your site returns to normal without risking data loss.

2. Internal Server Error (500 Error)

The 500 Internal Server Error is a generic error message indicating that something has gone wrong, but the system cannot specify what.

Possible Causes

  • Corrupted .htaccess file

  • Plugin or theme conflicts

  • Exhausted PHP memory

  • Server misconfigurations

How to Fix It

Regenerating the .htaccess file often solves this problem. You can also increase the PHP memory limit or deactivate plugins to find the source. If the issue persists, it could be related to your server environment, requiring expert diagnostics.

3. Error Establishing a Database Connection

This error occurs when your website cannot connect to the database—typically due to incorrect credentials or database corruption.

Common Causes

  • Wrong database name, username, or password

  • Corrupted database tables

  • Overloaded server or traffic spikes

  • Hosting issues

How to Fix It

Check your database credentials in the configuration file. If these are correct, use database repair tools provided by your hosting panel. In situations involving database overload, upgrading your hosting plan or optimizing your database may be necessary.

For complex database issues, relying on a Virtual oplossing expert WordPress development service ensures that advanced troubleshooting is handled safely and efficiently.

4. WordPress Login Redirect Loop

Sometimes, users face an issue where WordPress keeps redirecting them to the login page even after entering correct credentials.

Why It Happens

  • Cookie issues

  • Plugin conflicts

  • Incorrect URL settings

  • Corrupted .htaccess file

How to Fix It

Clearing your browser cookies and cache often resolves this. Updating the site URL settings or regenerating the .htaccess file can also help. If the issue stems from a plugin conflict, deactivating plugins and reactivating them one by one is the best approach.

5. White Text and Missing Buttons in the Editor

This error affects the WordPress visual editor, where certain buttons disappear, or text becomes white and unreadable.

Reasons Behind the Error

  • JavaScript conflicts

  • Corrupted TinyMCE files

  • Permission issues

  • Browser cache problems

How to Fix It

Refreshing your browser cache, ensuring all theme and plugin files are up to date, and checking user permissions usually resolve this issue. If the problem persists, replacing editor files may be necessary.

6. WordPress Memory Exhausted Error

This error appears when your website tries to utilize more memory than allowed.

Causes

  • Heavy plugins

  • Large themes

  • High traffic

  • Insufficient hosting resources

How to Fix It

Increasing the memory limit resolves this issue in most cases. You can also reduce the number of heavy plugins, optimize image files, or upgrade to a more powerful hosting plan.

7. 404 Page Not Found Errors

Sometimes pages on your WordPress site may show 404 errors even though the content exists.

Common Reasons

  • Broken permalinks

  • Deleted or relocated content

  • Plugin conflicts

How to Fix It

Regenerate permalinks through the settings panel. If the issue involves content relocation, updating URLs or redirections will fix it. For recurring issues, reviewing plugin configurations is essential.

8. Connection Timed Out Error

This error happens when your site takes too long to load, causing the server to stop the connection.

Typical Causes

  • Overloaded servers

  • Heavy plugins

  • Low hosting resources

  • Slow queries

How to Fix It

Remove unnecessary plugins, optimize your website performance, or upgrade your hosting plan. Checking for queries that consume too many resources is also helpful.

9. WordPress Update Failures

Sometimes updates for WordPress core, themes, or plugins fail, leaving your site stuck in maintenance mode.

Reasons

  • Interrupted processes

  • Permission errors

  • Server issues

How to Fix It

Deleting the temporary maintenance file often solves the issue. Ensuring proper permissions and enough server resources also prevents future update failures.

10. Sidebar Appearing Below Content

This layout issue occurs when the sidebar unexpectedly shifts below the main content.

Causes

  • Broken HTML structure

  • Theme coding issues

  • Plugin conflicts

  • CSS errors

How to Fix It

Fixing the underlying layout structure resolves the issue. Checking recent changes or disabling conflicting plugins is equally important.
