Gratitude.
This solved my problems.
All ok now.
Thanks for your reply. I was using Edubin for Tutor LMS. I deleted and installed Tutor Start but I would like to use another theme. I'm installing a DIVI PRO theme. Do you have any that you recommend me?
I'm not a programmer. And this change came out of my area of expertise.
It's simpler to change the theme and reinstall. haha
Great. This worked for me too. Gratitude. But it still has some bugs. Hahaha
