HI, I have just installed ISPconfig 2.2.11 on Fedora core 5 x86_64 without any error. But i hit exact the same problem as described in this thread: -- http://www.howtoforge.com/forums/archive/index.php/t-450.html I have read this thread many times and am sure mine is a fresh install, mysql is on listening on tcp. doctype is in the table. But i still get : " The following error occurred: The requested document type does not exist. " The only thing I can think is my database server has default utf8 character set. Does this matter? Please help. I have bumped my head into the wall for a couple of days !! Thanks a lot.
