Hi, thanks for this. we followed your instructions on the test site that we set up, and we got this error:
So, from there, we set up a fresh test site using launch.joomla.com and tried running it, on there, the other languages didn't appear, and when viewing the menu from the Joomla admin panel, we get the following error (Which was the original error message) - It did at least create the article duplicates, and then we can see the problem with the articles not displaying in the back end is now fixed,
If we create a new menu item manually after the translation process is completed, and link that menu to one of the translated articles, that works in both Cassiopeia and the RocketTheme template....
....but, the translation tool is still removing the opening H3 tags in the articles
On the launch site, we are using PHP 8.0
