I can only log in when I change my password. Is there something I am missing? (11th day UPDATE)

I can only log in when I change my password. The password-changing process manages to log me in. I cannot log in, at all, in any other way. Not in any internet browser, even in clean installs. When I click the login button it just keeps spinning forever. The Jerboa app is the only thing giving me any info because it always says, “Incorrect Login”.

This has been happening since I registered for the first time fourteen days ago. I have been trying every day, at different times, from different browsers even from different internet connections. The only relevant this that happened it was one day that for a split second I was logged in as another user, Marmaduke?, but this is just an anecdote I have no way of verifying this.

I do not know why this happens or how to solve it. I am sorry. I just don’t know what else to do.
