the problem I have does happen with existing contents, that were created with the Classic Editor.
"Unfortunately, we could not determine which editor you used from the previous records because the database records indicated the opposite."
What do you mean by that?
The pages I mentioned were created with the classic editor and your sql query returns "wpml".
Once someone edits the translation the query returns "acf".
When troubleshooting any issue, it is essential to check the records from the database. You used CTE to translate some posts, but upon checking the database, it indicated that you used ATE instead.
To further investigate this issue, I created a post to reproduce it, but unfortunately, I was unable to do so. Therefore, I kindly request that you change the editor by running our SQL comment.
In the future, if the editor changes again, please inform us so that we can continue to investigate any potential issues.
