@xmdath I tested my friend's opera mini cause it's a way old version but the problem remains.On her chrome everything is good,but chrome needs a lot of data and a lot of memory space.I'm kinda desperate??

I own the latest version of opera mini and I have exactly the same problem.I can't log in my account,nor sign up for a new one.Please,fix it,my internet connection is very slow where I live and opera was always my solution to this.
