@nendara Had same issue.
What I did to fix it:
– find the php file in the template folder in the tutor plugin (through plugin editor or ftp)
– remember the folders it was in (for example /templates/dashboard/quiz-attempts/ for quiz-reviews.php)
– in your theme folder, create a folder called “tutor”
– in there you recreate the folders you found that php file in, except “templates” (in the example you’ll create /your-theme-name/tutor/dashboard/quiz-attempts/)
– copy the php file (in the example quiz-reviews.php) in there
In WordPress, go to theme editor, edit the php file, remove the author part, and save.
If the folder creation was done correctly, the author won’t be showing up anymore as the plugin now uses that php file instead of the one within the plugin.
If something goes wrong on that page, due to bad php lines, you can simply fix it there or delete the new file if you really can’t find it.
