Where did backup/restore go?

[@silviolopez1194]

Good morning @wisecat, I need your help, I updated the server from version 3.11 to 4.0.5 and the process was completed without problems, but when trying to make a backup copy of the course, it sends a warning that " Class 'mod_assign_renderer ' not found", I am trying to carry out the process from the command line, but I do not have clear information where the backup is saved and how it is done, I would greatly appreciate your help with the process of creating a course from a previous backup. Thank you

You're not alone with this problem. It appears to be caused by a problem in the theme you are using. Try going back to boost if possible and make sure the theme is up to date and compatible with Moodle 4. You can force the theme to boost by adding the following line to your config.php file: $CFG->theme='boost'; Alternatively, you can move the theme you are using out of the Moodle temporarily (if that makes sense). Send me an email if you need more help with this. Good Luck! See also; moodle.org/mod/forum/discuss.php?d=433808
