This thread is resolved. Here is a description of the problem and solution.
If you're experiencing an Internal Server Error when clicking through links on translated version of your website, the issue might be related to the .htaccess file or permalink settings.
We recommend trying the following steps:
1. Visit the following documentation: https://wpml.org/errata/htaccess-is-rewritten-with-language-folder/
2. Re-save your permalinks by going to Settings >> Permalinks in your WordPress dashboard and clicking the 'Save Changes' button.
