Overview
A 500 Internal Server Error is a general server-side error that means something is wrong with your website, but the server can’t display a more specific message. It is usually caused by a broken configuration, plugin issue, or file error.
Common Causes
- Corrupted `.htaccess` file
- Faulty WordPress plugin or theme
- Incorrect file permissions
- PHP memory limit issues
- Broken or missing core files
Step-by-Step Fixes
1. Check your .htaccess file (most common fix)
- Log in to DirectAdmin File Manager
- Go to `public_html`
- Find `.htaccess`
Fix options:
- Rename it to `.htaccess_old`
- Then refresh your website
If the site works after this, regenerate the file in WordPress:
- Go to Settings → Permalinks → Save Changes
2. Disable plugins (WordPress sites)
A bad plugin is a very common cause.
- Go to File Manager
- Navigate to: `wp-content/plugins`
- Rename the folder to: `plugins_disabled`
Check your website again. If it works, a plugin is the cause.
3. Switch to a default theme
- Go to: `wp-content/themes`
- Rename your active theme folder
WordPress will switch to a default theme automatically.
4. Check file permissions
Incorrect permissions can break your site:
- Folders: 755
- Files: 644
You can adjust this in File Manager.
5. Increase PHP memory limit
If your site is overloaded:
- Open `wp-config.php`
- Add this line:
`define('WP_MEMORY_LIMIT', '256M');`
6. Check error logs
DirectAdmin provides logs that can help identify the exact issue:
- Look for Error Logs in your control panel
- This will show the specific cause of the 500 error
Important Notes
- Always back up your site before making changes
- The error is usually caused by recent changes (plugin, theme, or file edit)
- Fixing one issue at a time helps identify the cause
