I set up WordPress on a self-hosted site 2 weeks ago but now my install is not accepting me logging in as admin ("ERROR: invalid username" when I try and login as "admin"). I also set up a standard user account which is also not accepted.
The weird thing is that if I click on the "Lost Password?" link to be sent a reset link, I do receive the email and can successfully change my password (but my install still won't let me login afterwards)?
Is there something obvious that I am missing that I'm doing wrong?
Any suggestions gratefully received!
