Background of the issue:
I am trying to resolve a warning in the Dashboard that indicates some taxonomy terms are out of sync between languages. This issue suggests that content in some languages might not have the correct tags or categories. I attempted to synchronize the taxonomies by checking the Taxonomy Sync page, but it doesn't show any missing terms. The issue can be seen at the following link: hidden link
Lucas Vidal de Andrade managed to fix it, but a few minutes later the message came back.
Symptoms:
There is a warning in the Dashboard stating: 'Some taxonomy terms are out of sync between languages. This means that content in some languages will not have the correct tags or categories.' However, the Taxonomy Sync page doesn't show any missing terms.
Questions:
Why is there a warning about taxonomy terms being out of sync when the Taxonomy Sync page shows no missing terms?
I was just about to ask you for a status update, and suddenly noticed that the warning is gone. I don't know if this was fixed by something I did or something you did.
This is what I did that may have fixed it.
A couple of hours ago, I went to the Art Categories taxonomy and changed the current admin language to Hebrew (English is the source language). It listed all the Hebrew translations of the terms, and I noticed the first term was written in English and is a term that doesn't exist in the source language. I deleted it. Afterwards, I checked again, but the warning was still there.
A few minutes ago, there was a strange background for some columns in a page I was editing, but only on the front end. I managed to fix it by going to Divi Theme Options > Builder > Advanced, and clicked [Clear] on "Static CSS File Generation". This fixed the page I was editing.
I wonder if it the combination of these two fixes also fixed the WPML warning about the taxonomy not being synced.
Thanks for sharing the results. It's hard to tell, as in minimal (with all unrelated plugins deactivated) the notice behaves differently.
The message has no impact on the functioning of the website, so if it doesn't appear again, there should be no issues. Please monitor for the next few days, if the message pop up again and let me know. Thank you.
As the warning seems to be gone, I will remove the plugins your team installed ("Database Manager - WP Adminer" and "All-in-One WP Migration and Backup"), and demote your user.
