When I access my gallery for a couple of hours ago I got this message:

Critical error
There was an error during the request to the database

Early today I uploaded a few pictures to the gallery and then it worked fine. I haven't changed any of the files today that belongs to the gallery. I have search the forum, but I can't find any thread that says what I shoud do so I hope someone can help me with this.
