OK @Cookie Monster.
I need the solution to launch my forum, that why I call it's urgent ... Lol
One more question, why https is not working (Page not fully loading), while on http protocol page is fully working?
The problem got solved, but another error is occurred. Now the display of page is so rough.
Even it not showing any logo just like 2,4 lines!
I think its https problem, I'm using cloudfare SSL
