I'm using WP 3.0.1 , and Buddypress 1.2.6 , Theme - Blogs-Mu theme (from WPMU DEV)
I was using BP 188.8.131.52 , and the theme worked fine.
I just upgraded to BP 1.2.6 , and now found a problem ...
Hide admin bar for logged out users? is checked to Yes ...
Now logged out user view a white space at the top (look in the image, a whitespace just below the addressbar) , if the admin bar visibility is turned on for guest visitors the admin bar is displayed instead of the white space ..
While using it with BP 184.108.40.206 there was no such white space ?
If any other information is need please gladly ask for it , i will try my level best to provide as much information possible , I just want this issue resolved .
