Are there specific solutions for fixing a 403 Forbidden error when operating a WordPress website?

For WordPress sites, 403 errors often stem from plugin conflicts, theme issues, or corrupted .htaccess files. Specific fixes include: 1. **Deactivating Plugins:** Deactivate all plugins via FTP (rename the 'plugins' folder) and reactivate them one by one to identify the culprit. 2. **Default .htaccess:** Regenerate your .htaccess file by going to Settings > Permalinks in your WordPress admin and simply clicking 'Save Changes'. 3. **Theme Issues:** Switch to a default WordPress theme (like Twenty Twenty-Four) to see if your current theme is causing the problem. 4. **File Permissions:** Verify that your WordPress files and folders have the correct permissions (644 for files, 755 for folders).
