Understanding 500 Internal Server Error

The 500 Internal Server Error is one of the most frustrating errors. Here's how to fix it step by step.

Solution 1: Check .htaccess File

Corrupted .htaccess is the #1 cause:

# Rename .htaccess temporarily
mv .htaccess .htaccess.backup
# Test your site - if it works, your .htaccess was the issue

Solution 2: Increase PHP Memory Limit

Add to wp-config.php or .htaccess:

define('WP_MEMORY_LIMIT', '256M');
# Or in .htaccess:
php_value memory_limit 256M

Solution 3: Check File Permissions

# Correct permissions:
find /path/to/site -type d -exec chmod 755 {} \;
find /path/to/site -type f -exec chmod 644 {} \;

Solution 4: Disable Plugins (WordPress)

Rename plugins folder via FTP:

wp-content/plugins → wp-content/plugins-disabled

Solution 5: Check Error Logs
