[Resolved] Translation returing 500 error

Problem:
After updating WPML to the latest version, the client is unable to translate content and encounters a 500 error when attempting to use the string translation or open the WPML support tab. The issue began after URL slug manipulations were made, which might have caused disruptions in the translation engine.
Solution:
We recommend enabling the debug log to identify the specific cause of the 500 error. You can follow the instructions here: https://wpml.org/documentation/support/debugging-wpml/. After enabling the debug log, please share the log files with us for further analysis. If the problem persists, consider reverting to a previous stable version of WPML and its components, as this resolved the issue temporarily for the client.

Please note that this solution might be outdated or not applicable to your specific case. We 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. If the issue continues, please open a new support ticket at WPML support forum for personalized assistance.
