Problem: While linking speakers to events and connecting speakers in different languages, the site encounters a 503 error after several operations. The logs show hundreds of lines indicating a database deadlock error. The only way to restore the site is to reset the PHP processes. Solution: If you're experiencing similar issues, we recommend updating WPML to see if the problem persists. The client confirmed that after updating WPML, the deadlock issue did not reoccur. If you do not see updates available in the plugin page, visit the WPML registration page to check for updates and update from there.
Please note that this solution might be outdated or not applicable to your case.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 persists, please open a new support ticket.
