It is not possible to sign up for NetCAT 9.0 program, because going to the sign up form  only displays empty page except the typical dashboard menu on the right hand side.
For the record we are looking into it but all attempts to resolve the issue failed so far. Will be fixed next Thursday at the latest.
I have reverted my changes but to no avail:
Honzo, can you please fix the access privileges again? It seems like SVN commits break the access. Thanks.
Works like a charm. Thanks for the fix Honzo!
