Problem:
After installing the WPML Multilingual CMS plugin, the site admin panel stops working and displays a critical error. The error message indicates that the class 'DOMDocument' is not found, which is part of a PHP extension that may not be enabled on the server.
Solution:
If you're experiencing a critical error after installing the WPML Multilingual CMS plugin and the error message mentions that the 'DOMDocument' class is not found, we recommend checking if the PHP XML extension is enabled on your server, as the 'DOMDocument' class is part of this extension.
