Problem: The client was unable to configure WPML after activation due to multiple fatal errors, including a 504 AJAX Error and a PHP Fatal Error indicating that the maximum execution time was exceeded. The issue was suspected to be related to the 'sitepress-multilingual-cms' plugin. Solution: We investigated the issue and discovered that it was caused by a corrupted key in the database. After fixing the corrupted database key, we advised the client to continue configuring WPML and to install the WPML String Translation plugin, which is necessary for full functionality. If this solution does not resolve your issue, or if it seems outdated or irrelevant to your case, we recommend opening a new support ticket. We also highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins.
