Understood and thank you for the replies. I have since went back and disabled all plugins as well as manually fixed the htaccess file per WP codex. I am still getting that white screen of death I would say 25% of the time I try to navigate back to the main site from a user blog. Still think the best solution is to do a fresh install? I certainly can do that, but am hoping to be able to manually fix the broken code. Anyone have another suggestion?
Well, it seemed to work for a while. Problem I am having is after browsing the user created sub site, the main site crashes on me. If I try to navigate back to the main URL, I get nothing but a blank screen. Strange….
