I have 4 browsers installed on my PC.
In one I have friendica open with the user administrator.
On another is the user I normally use.
A week ago I added a new user to friendica, but I can't get into his account through any browser. Not even on my mobile phone.
After that, I tried to log in to the account of my normal user through another browser, both on my PC and on my phone, but I always get the same error.
At the moment I seem to be able to access my normal account via just the same browser (the same with the admin).
