Cannot open WPML/Settings page -> fatal error

This thread is resolved. Here is a description of the problem and solution.

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If this solution does not resolve your issue, or if it seems outdated or irrelevant to your case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix,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

Carlos Rojas Supporter Languages: English (English ) Spanish (Español ) Timezone: Europe/Madrid (GMT+02:00)	Hi there, This is the forum ticket we will continue working on this issue I have set your next answer private so you can share the access credentials to the staging site. Looking forward to your message.

Károly Farkas	Hi Carlos, Since you moved the chat to thread, I was unable to "wake up" the site, so I could not clone the site to staging. The server was restarted several times, and without any traffic on the site, the sql server receives 600000-700000 queries per 5 seconds. This is the pattern: SELECT translation_id FROM wp_icl_translations WHERE element_type='tax_pa_meret' AND element_id=11316 element_type and element_id varies, but almost all the queries are like this. Did you start any process, or cleared some cache maybe? It is important to know because if this is the case, we can expect it to finish some time and we just have to wait for it. If not, then something seriously messed up in the site and must be repaired onsite. Thank you

Carlos Rojas Supporter Languages: English (English ) Spanish (Español ) Timezone: Europe/Madrid (GMT+02:00)	Hi there, I added a function to recreate any missing WPML table from the database and then removed it. Please double check that the function was removed from the functions.php file in the theme. Other than that, I made no other changes because the site was too slow.

Károly Farkas	Hi Carlos, Thank you for the information. I disabled the function, and now the site is back. I duplicated the site to a staging environment, which you can find at test.fishinda.com. All the credentials are the same as I provided eariler. Please feel free to try anyting in the this site copy. The first problem would be the fatal error, given by WPML/Languages menu item, and then the performance issue. They might be related, but if not, then I guess it's better if the performance topic goes to a different thread.

Carlos Rojas Supporter Languages: English (English ) Spanish (Español ) Timezone: Europe/Madrid (GMT+02:00)	Hi, Thank you for creating the staging site. I don't know exactly what is the issue on the staging site, but the issue on the live site is solved already. Can you confirm that the issue in the production site is solved?
June 17, 2024 at 9:19 am #15744171
Károly Farkas	Yes I confirm that I am able to access WPML / Languages admin page on production site, but still gives fatal error on staging site. We changed nothing on either of the sites. Do you have any idea what could fix the issue on the production site?

Carlos Rojas Supporter Languages: English (English ) Spanish (Español ) Timezone: Europe/Madrid (GMT+02:00)	Hi, After the workarounds we applied the issue must have been solved, but we were probably seeing an outdated cache version with the error. Once the cache was flushed the error disappeared.

Károly Farkas	Ok then I should just wait for the staging site to flush its cache? I tried various methods to clear the cache on the staging site, (deleted transients, purged cache, reinstalled wpml again) but the "Languages" page still gives fatal error. How can I solve this issue if happens again in the future without bothering you?

Carlos Rojas Supporter Languages: English (English ) Spanish (Español ) Timezone: Europe/Madrid (GMT+02:00)	Hi, The issue won't appear again in the future because the problem in the database is solved. To solve the issue on the staging site you should apply the same workaround and then I recommend you to deactivate/activate all plugins to see if the cache memory is flushed.
June 17, 2024 at 1:10 pm #15745717
Károly Farkas	I tried to run the workaround function that you inserted formerly in theme functions, with every other plugin inactivated, but still no luck. However it has no importance right now, because the problem on the production site is solved, so I close this ticket as solved. Thank you for your assistance.
