I made a mistake importing my database, I deleted my own account ... I tried to use it again by changing the user_id, changing a lot's of stuff but none worked. My account exists and doesn't exist at the same time...
What can I do know that my forum is running again to recover my account, or, if impsosible, juste delete my former account (now, he's like a guest)
We are the same person but one is alive and the other doens't exist xD
 : I forgot to say that I was the super-admin and it was quite a mess to get my forum back because of that xD
