Website not working at all

The albums on my website, or better probabely the whole backlight part stopped working. Without any change. I can no longer log in to backlight also. There seems to be a database lock. Älmums on the ipad return:

The login to backlight returns

Copying and deleting the backlight and the ttg-be did the trick.
