Fix WordPress 500 Internal Server Error
The 500 Internal Server Error is a generic server-side error that can be caused by dozens of different issues. Unlike the White Screen of Death, it doesn't give you any clue about what went wrong. We dig into server logs, PHP configuration, and file permissions to find and fix the exact cause.

What Causes 500 Errors in WordPress
- .htaccess corruption — The most common cause. A plugin wrote bad rewrite rules, or the file got corrupted during an update.
- PHP version incompatibility — Your host upgraded PHP and a plugin isn't compatible with the new version.
- Memory limit exceeded — PHP ran out of memory processing a heavy page or admin operation.
- File permission errors — Incorrect file/directory permissions preventing PHP from reading or executing files.
- Corrupted plugin/theme — A failed update left partial files that PHP can't parse.
- Server configuration — mod_security rules blocking legitimate requests, suPHP/CGI handler issues.
Our Diagnostic Process
We don't guess — we diagnose systematically:
- Check PHP error logs and server error logs for the exact error message
- Test .htaccess by temporarily replacing with default WordPress rules
- Verify PHP version compatibility with installed plugins/themes
- Check file permissions and ownership
- Test with default theme to isolate theme vs. plugin issues
- Review server configuration (Apache/Nginx, PHP handler, mod_security)
