403 Error — Can’t Log In.

I’m really close to giving up hosting this on my server.

When I try to log in with the admin username and assigned password, I get a 403 error.

I’ve followed the recommendations about log in problems.

One thing I’ve noted, after I’ve deleted the db and re-installed (which I’ve done like 5 times), the login screen appears already stating that I’ve entered an incorrect log in…then I enter admin and the pw and that takes me to the 403 screen.

Any help would be appreciated. Thanks!
