Hello everybody, I know what you are thinking right now. "Here comes another idiot who didn't bother to search for the solution in the forum". Actually I've been searching the web for the solution. I know it's a white space at the end of the begining of the file. The thing is I've downloaded lylina and pligg from sourceforge. And both should not have this white space code inserted. I've even check all the php files for whitespaces. It's driving me cuckoo. As I have been trying to solve this problem for 2 weeks now. This is the first time I'm posting after scouring the internet for tips. I'm using Apache 2.2, PHP 5.1.4, Mysql 5.0.1, XP, Firefox, IE 6. Please help me before I destroy my monitor due to my rage. I left you now with the error I get from lylina.
