Hello everyone.
I have a problem regarding logging on my website that runs on wordpress.
Yesterday I upgraded wordpress to 3.3.1. Everything worked fine till this morning when I couldn't log anymore on wordpress, and got a blank page.
The username and password are correct.
I've deleted all the plugins from wp-content/plugins folder to see if there is a problem with them.
I've made the upgrade again and no result.
I even tried to upload the older version of wordpress, again, and no result.
The website is running very well.
I cannot understand why yesterday it worked very well, and without any modification, I cannot access the Dashboard any more.
ps. I've made a full backup for my website and database.
