Now I installed mambo to new directory and copied the old database to new install, but the problem is still there! I also installed one mambo more and just docman component to it and it works fine with the default mambo..
I also have one other site one the server and docman works fine in it.
So what on earth could be the problem in the problem site? I think it is not empty line in php file problem, but something else. What other stuff could mess up the headers.. . .. heeeeelp!!
