Hello. I know this thread is old, but I am having the exact same problem and can't figure it out. I tried the last version 3.1 and the 3.2-beta, same issue... tried many browsers, my iPad, turned off all the extensions of my browser (AdBlock, etc).
Where am I supposed to "enable cookies"? Server-side or client-side?
Everything else is correct: permissions, and so on.
Help!
Thank you.
