Hello,

i upgraded from latest stable release (2.72.4+171110) to 3.0.0-beta with comfortUpdate yesterday.
Now I have some troubles with it. I used latest different browsers.
E.g.: Adding a subquestion does not work (nothing happens), can't move subquestions up and downwards anymore, pressing "Mandatory" button does not lead in anything, group and question structure is not displayed sometimes.
... and more

Whats the safest way to downgrade back to 2.72.4+171110?

Hi,

Sorry to hear about your problems. Did you backup your database before upgrading?

I followed those instructions and it worked!

OK, great!
