Thread:Project:Support desk/Strange digits appearing on wiki pages/reply (2)

Yes, I tried to disable AuthJoomla2 but in vain. The problem doesn't disappear :( When I open html code of these pages, I can see that upper "digit" appears before <!DOCTYPE html> and "0" after the closing tag. I think the problem is in some header function which outputs starting and ending tags but i can't figure out . plz give any hint.
