I use wordpress 3.0 yesterday , I can login in and post articles,I didnt change anyting. Today, I input the username and password, When click submit, There is only a black page appears. I am sure theusername and password are all right, I have reinstall the blog, But now the same question appears. Please help me.
I had this happen to me a little bit ago... Did you happen to install any plugins lately that would of caused the problem. I had a plugin that didn't work with the current version of WP and left me with a blank page... I had to go into the backend of the website and delete the plugin from the plugins folder... just a suggestion hope it helps
