1. Internal Server Error (500 Error WordPress)

Infographic explaining WordPress 500 Internal Server Error symptoms and causes.

What is a 500 Internal Server Error? It is a generic “catch-all” error message indicating the server encountered an unexpected condition that prevented it from fulfilling the request. For WordPress users, this typically stems from corrupted files or plugin conflicts.

Symptom

A blank screen or a “500 Internal Server Error” message appears across the entire site or specific pages.

Likely Cause

Common culprits include a corrupted .htaccess file, reaching the PHP memory limit, or a faulty plugin update.

What to Check

Log in via FTP and rename your .htaccess file to .htaccess_old to see if the site loads. If it does, go to Settings > Permalinks and click “Save” to generate a new one.

When to Escalate

If the error persists after resetting the .htaccess and disabling plugins, you need emergency WordPress support to check server logs for deep-seated configuration issues.

2. Error Establishing a Database Connection

Your website is a collection of files and a database. When they stop talking, your site stops working.

Symptom

A plain text message stating “Error Establishing a Database Connection” appears instead of your website.

Likely Cause

Incorrect database credentials in your wp-config.php file or a corrupted database table.

What to Check

Verify that your database username, password, and host are correct. You can also add define('WP_ALLOW_REPAIR', true); to your wp-config.php to attempt a native repair.

When to Escalate

If credentials are correct and the site still won’t connect, your WordPress webmaster needs to verify if the database server itself is down or throttled due to traffic spikes.

“A slow or broken database connection can lead to higher bounce rates and significantly lower conversion rates for e-commerce sites.”

3. The WordPress White Screen of Death (WSoD)

Symptom

A literal blank white screen with no error message at all, leaving you with zero clues.

Likely Cause

Usually caused by a script reaching the memory limit or a fatal error in a theme or plugin.

What to Check

Increase your PHP memory limit in the wp-config file. If that fails, disable all plugins via the database or FTP.

When to Escalate

When you cannot access the admin dashboard or the FTP, professional WordPress support services are required to enable debugging mode and pinpoint the script failure.

4. Connection Timed Out

Symptom

The site takes too long to load and eventually displays a “Timed Out” message.

Likely Cause

This happens when your website is trying to do more than the server can handle, often due to heavy plugins or poor server optimization.

What to Check

Deactivate resource-heavy plugins (like broken link checkers or heavy backup tools) and check your internet connection.

When to Escalate

If your site regularly times out, your host may be over-provisioning their servers. This is a sign you need high-performance managed SEO hosting.

5. Stuck in Maintenance Mode

Symptom

Your site shows “Briefly unavailable for scheduled maintenance. Check back in a minute” even after an update is finished.

Troubleshooting guide for WordPress stuck in maintenance mode showing server errors and escalation steps.

Likely Cause

WordPress creates a .maintenance file during updates. If the update is interrupted, the file remains.

What to Check

Delete the .maintenance file from your root directory using FTP.

When to Escalate

If the file keeps reappearing or your updates constantly fail, your server permissions may be misconfigured.

6. PHP Syntax Errors

Symptom

A message like “Parse error: syntax error, unexpected…” followed by a file path.

Likely Cause

A typo in your code, that usually occurs after manually editing functions.php or adding a code snippet.

What to Check

The error message tells you exactly which line of code is broken. Revert the last change you made.

When to Escalate

If you cannot access the file editor to fix the typo, contact your WordPress support services to restore a clean version of the file.

7. Exhausted Memory Limit

Symptom

An error message stating “Fatal error: Allowed memory size of X bytes exhausted.”

Likely Cause

Your WordPress site or a specific plugin requires more RAM than your hosting environment is providing.

What to Check

Edit your wp-config.php file and add define('WP_MEMORY_LIMIT', '256M');.

When to Escalate

If your host limits your ability to increase memory via wp-config, they are restricting your site’s growth. You need a host that supports high-performance business applications.

8. Image Upload Failures

Troubleshooting guide for WordPress image upload errors showing server issues and escalation steps.

Symptom

An “An error occurred in the upload. Please try again later” message when adding media.

Likely Cause

Incorrect file permissions on the server or a temporary server glitch.

What to Check

Ensure your “uploads” folder permission is set to 755.

When to Escalate

If permissions are correct but uploads still fail, your server may be out of disk space or running an incompatible PHP version.

9. Login Page Refresh and Redirect Issues

Symptom

You try to log in, but WordPress simply refreshes the login page and redirects you back to it without an error.

Likely Cause

Incorrect site URL settings or corrupted cookies.

What to Check

Clear your browser cookies and cache. Ensure your siteurl and home values in the database match exactly.

When to Escalate

If your URLs are correct and you are still locked out, it may be a security firewall blocking your IP, requiring server-side intervention.

10. SSL and Mixed Content Warnings

Symptom

The “Not Secure” warning in the browser bar despite having an SSL certificate installed.

Likely Cause

Some assets (images or scripts) are still loading via HTTP instead of HTTPS.

What to Check

Use a plugin like “Better Search Replace” to update HTTP links to https in your database.

When to Escalate

If the SSL certificate fails to renew or install correctly, your host should handle the 500 error WordPress and SSL handshakes automatically.
