500 Internal Server Error

This thread is resolved. Here is a description of the problem and solution.

Problem:
You have WPML installed on an Elementor website and encountered a 500 Internal Server Error on all language pages except for the default language after installing The Events Calendar plugins. The issue persists even after changing PHP versions and occurs only when WPML is active, regardless of the status of other plugins.
Solution:
We suspect this might be related to an issue where

.htaccess

is getting overwritten due to WPML settings. We recommend trying the workaround described in this article: https://wpml.org/faq/why-is-htaccess-getting-overwritten-with-the-language-folder-on-my-wpml-website/

If this solution does not resolve your issue or seems irrelevant due to being outdated or not applicable to your case, please open a new support ticket.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. For further assistance, you can contact us directly through our support forum.

jeanP-10	I have WPML installed on an Elementor website. I had no problems with it until I tried to installed The Events Calendar plugins. I immediately got a 500 Internal Server Error on all language pages except for the default language. I set up a staging environment to troubleshoot the problem, and The Events Calendar support was involved but unable to pinpoint the cause, until they noticed that the 500 error occurs only when WPML plugin is installed and all other plugins are deactivated. See this screencast: hidden link But it only seems to occur when TEC has been installed previously (even if subsequently deactivated). Could you help with this issue? I have changed the php version from 8.4 to 8.3 after reading in another support post that that could be an issue. The problem still persists. Otherwise all plugins, themes and WordPress version are current.

jeanP-10	The problem still persists after going through the steps suggested by your AI chatbox, including running a code in the functions.php file.
