I tried logging in from another computer and got the same problems. Same with a completely fresh re-install —?it works perfectly fine up until the point where I have to log in, and then I get told that the password is wrong.
The theme I tried to install was Zeebusiness: https://www.ads-software.com/themes/zeebusiness
I’ll contact my webhost and see if they know anything, but if anyone else have ideas of what to try I’m all ears!
ETA: I’ve talked to my web host and according to them there shouldn’t be any problems with the server that could cause this problem.
