MyBB Community Forums

I seem to have somehow extended the length of the panel at the top of my forum.  It happens every time I try to create a new theme. I think that I may have currupted the MyBB Master Style.  Can someone please tell me how to get it back to normal.  I am a complete newbie to MyBB.  Thank you for any help that you can give me.

Without seeing any source code it's hard to isolate the problem, but judging by the screenshot it looks like you can resetting the templates might work.

Go to: Templates > Your Theme > Header Templates > Then for the Header template click options > Revert to Original

If the problem persists try doing the same for the Default Templates
