When I try to change the image, I get this error Can not create file. I already have the persmisians correctly 755 and 644
The course is a back-up of a course from another moodle, which uses the grid format.
But if I go to another course and I put the grid format, it changes the images.
I have moodle 3.2.5 and the 18.104.22.168 format
How can I solve it?
