Florian	Background of the issue: I am trying to access a page on my website, but sometimes I encounter an error 500. I already tried this fix but it doesn't work: https://wpml.org/errata/php-8-3-x-fatal-error-maximum-call-stack-size-reached-due-to-possible-infinite-recursion/. The issue can be seen on this page: hidden link. Symptoms: We are getting an infinite recursion within WPML, resulting in an error 500 page.

You may be facing this issue because of compatibility conflicts. To make sure, please follow the following steps. a) Backup your site first[Mandatory] b) Switch for a moment to a WordPress default theme like 2025 c) Deactivate all the plugins that are not related to WPML d) Then check if the issue exists or not e) If the issue is gone, activate the plugins as a group of three or four to find which one has an interaction issue f) Switch back to the original theme of the site Which hosting service are you currently using? Please share more details about your hosting plan. -- Thanks! Bigul
