Background of the issue:
I am trying to install the WPML plugin on my website. The DOM extension is already installed on the server. When I attempt the installation, I encounter a critical error. The error message is: "An error of type E_ERROR was caused in line 67 of the file /home/dalantec/public_html/wp-content/plugins/sitepress-multilingual-cms/classes/xml-config/class-wpml-xml-config-validate.php.
