I installed Wordpress several days ago, and everything was working well. Today when I went to log in, I got as far as the login page, but when I entered the correct user name and password, upon login I got a blank page. Not a password error, but a blank page. I've already tried all the tips here: http://codex.wordpress.org/Login_Trouble
Now I need some new ideas.
I've reset my password several times and it doesn't help. I only had one plugin and I've deleted that, and it didn't help. I had uploaded 32 different themes, and I was playing around with them when this happened. Could that be a problem? I've deleted a dozen of the themes from my server, and still have 20, but it hasn't helped yet.
Any ideas here? Thanks in advance for your help with this vexing problem.
