Problem:
The client was encountering a fatal error when trying to open the WPML/Languages menu item in their WordPress site. The error message indicated a call to an undefined function 'wpml_tm_load_tp_networking()'.
Solution:
We recommended the client to manually download and reinstall the 'WPML Multilingual CMS' plugin from the WPML account downloads section. Despite reinstallation and cache clearing, the issue persisted. We then accessed the site with the client's permission to investigate further. After troubleshooting, we added a function to recreate any missing WPML tables in the database, which resolved the issue on the live site. We advised the client to apply the same workaround on the staging site and to deactivate and reactivate all plugins to ensure the cache was flushed.

If this solution does not resolve your issue, or if it seems outdated or irrelevant to your case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix,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 problems persist, please open a new support ticket.
