Background of the issue:
I am trying to use the string translation on our old website. Upon activating the string translation plugin, I received a message on the wp-admin page. Link to a page where the issue can be seen: hidden link
Symptoms:
There is a problem with the String Translation table in your site. This problem is not causing a problem running the site right now, but can become a critical issue in the future.
Questions:
Can you please help us troubleshoot the issue?
I don't see wpml string translations plugin being enabled on the site, also, I don't have privileges to install it, so can you enable the WPML string translations plugin so I can test the issue further.
