Some one please Help me to solve this ASAP. my forum is down since 1 day.

Thanks in advance.

Are all core file edits made?

As stated in how to install text for google seo 1.6 i downloaded original mybb function.php and replaced the existing one with this. And used inbuilt function for changing core files, basically i followed the step through plugin installation where there was an option click here to apply core changes.

Hmm, looking at your forum is appears you're not eligible for support.

if not here then where can i get support for it?

Maybe MyBBCentral, MyBBSource, Hackforums. I don't know what their policies are.
