Thanks, that helped a lot but how does it deal with the changes in the css? will it bring the site header or the side bar back?
I tried the reset plugin on another, less important, site and it did clear all the design but I am not sure I want to go that far?
Basically, I need the site header and side bar back and a narrower content area. Will I be able install a different site from the library if I get rid of the over-simple one I previously installed?
