This thread is resolved. Here is a description of the problem and solution.
The client was experiencing an Internal Server Error when navigating the menu/page in a language that was not set as the default. The URL structure was incorrect, with the language code (/en/) incorrectly placed in the middle of the URL instead of at the end.
We reviewed the debug log and found no fatal errors related to the Internal Server Error. However, we noticed a PHP Notice error related to the 'The Events Calendar: Community Events' plugin. We deactivated this plugin and confirmed that the member pages then loaded correctly without the Internal Server Error. We provided a screen recording of the correct functionality for the client to review. We recommend the client to check their site after deactivating the plugin to see if the issue is resolved.
