My log is full of 404 errors pointing to

domain.com/rsc/css/fp02.css

This css file is actucally found in

domain.com/myblog/rsc/css/fp02.css

I cannot find where this file is being called from to correct
the small error in the code.

Anyone have anyone idea was fp02.css is used for, and where
it is being called from?

thanks in advance
