Something went wrong with my user profile. I cannot change it - I only get the following message on http://www.openstreetmap.org/user/EM311

"Application error

The OpenStreetMap server encountered an unexpected condition that prevented it from fulfilling the request (HTTP 500)

Feel free to contact the OpenStreetMap community if your problem persists. Make a note of the exact URL / post data of your request.

This may be a problem in our Ruby On Rails code. 500 occurs with exceptions thrown outside of an action (like in Dispatcher setups or broken Ruby code)"

I'm also unable to log into forums. So that here is the only way to ask for help

Thanks for your support!

Update: The problem has been solved. Thanks for your help!
