I have an internal server error on my drupal site only when I log in, when logged out everything is fine.
I was having problems with the default image-styles, they would not work (no thumbnail preview) so I created a new style (thumbnail2), deleted the default thumbnail style and replaced it with thumbnail2 style.
Any ideas how I recover from this?
So 2 problems:
1. get access to admin again
2. get default images styles to work
