It looks like I may have solved the issue by creating a separate Ad Group for each ad. Putting Ad Groups into placements seems to work, while individual ads (even if translated) don’t.
Thanks so much for your quick help.
I just added the code as is at the bottom of the current theme’s functions.php – it worked!
And you’re right, “upload_files” was sufficient, because Author role has that permission.
Thanks a lot for a quick response here! I should have found this on my own.
My experience with editing theme/plugin files is a bit limited. How exactly do I use the filter?
Shall I just insert the above line exactly as it is somewhere in the functions.php part of the theme via the “Editor”? Or is there more to it?
