Ok I solved my problem : I was over my SQL quota...

Hi everyone,
I am new on the forum and really need your help..

I think I have the same problem as Mandrew.
My website used to work fine until I had problem login into my admin account. No user is now able to post any new articles, I can't login as admin if i don't tick the remember me box (and somtimes, it even doesn't work) and I can't change anything in the administration: I only get the returning to where you were message.

I tried to upgrade but couldn't, so I went back to where i was. I tried to delete the content of the cache directory, except the index.html.
Finally, I tried to turn on the debug mode but I can't since no change in the administration is saved.

Here are the details of my website configuration :
