Problem: The client is unable to save changes to the translation preferences for posts and taxonomies in the WPML settings. After attempting to save, the settings revert to their previous state. Solution: We were unable to replicate the issue on a local copy of the client's site. We can edit and save any translation preference setting in WPML > Settings without any problems. Since the issue appears to be specific to the client's server, we recommend that you provide us with access so we can investigate the issue further. The solution here was server related: Set the value for “max_allowed_packet” configuration from 1M to 64M in the “my.ini” file. Please note that the solution provided might be irrelevant if it's outdated or not applicable to your case. If the issue persists, we highly recommend checking the related known issues, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If none of these steps resolve the issue, please open a new support ticket with us.
