Im posting this here as i havent found any bug report site.
On the site rankk.org/profile.py I've set it to "hide solved challenges". This worked perfectly.
However when I try to set it back to "Show solved challenges" I get the following error message:
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, [no address given] and inform them of the time the error occurred, and anything you might have done that may have caused the error.
More information about this error may be available in the server error log.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
I've tried in on different days and also other peopel I asked seem to have the same problem.

P.S.: If there is such thing as a site for bug reports please send me the link...
