Troubleshooting your WordPress website
⚠️ Important: Always make a full backup before attempting any troubleshooting steps.
This article provides guidance on investigating and resolving issues with your WordPress website. We recommend following the steps below in order. If an earlier step resolves your issue, there is no need to continue with the others.
While this article covers the most common solutions, it may not address every specific issue. In that case, you can contact a web developer or use our Extra Service "Problem Solving".

Check your log files

Enable WP_DEBUG
- Open your site's
wp-config.phpfile. - Add or update the following line:
define("WP_DEBUG", true);
- Any errors will now appear on your website.
Check your PHP version
- Verify which PHP version is currently active.
- WordPress and most plugins work best on PHP 8.1 or higher.

- Older websites might not support newer PHP versions immediately.
Reset your htaccess file
- Back up your current .htaccess file.
- Replace its content with:
# BEGIN WordPress
RewriteEngine On
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
RewriteBase /
RewriteRule ^index.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
# END WordPress
- Save the file and check if your website functions properly.
Disable your plugins
- Deactivate all plugins.
- Reactivate them one by one to identify the problematic plugin.
- Can’t access WordPress? Rename the plugins folder (e.g., to plugins-off) via FTP or File Manager.
- Refresh your website several times.
voorbeeld.cc with your own domain name in the file path domains/voorbeeld.cc/public_html.Clear the cache
- Clear the cache via your caching plugin, such as LiteSpeed Cache or W3 Total Cache.
- Your website might temporarily load slower until the cache is rebuilt.
Check PHP settings
