I'm having some troubles with the userforms module.
I have to languages, english and danish, which made some trouble because of the known languagebug, but I fixed it in phpMyAdmin.
However, I get and Internal Server Error 500 when I submit the userform in danish, it works fine in english.
Please test it for your self here in danish: http://www.galleripulsart.dk/tilmeld-invitationsliste/
And here in english: http://www.galleripulsart.dk/sign-up-for-invitations/
Hope someone can help me, I believe it's just an database-thing I've forgot or messed up, but I'm not sure...
