Oops, I seem to have made a blunder and now am not sure how to fix it.
My site which is just about done was at pacificcoastpilot.com/wp. I wanted to see what would happen if I went to dashboard/settings/general and chopped /wp off the site URL. Went to pacificcoastpilot.com and nothing was different. The dummy index page was still there. So went back to dashboard/settings/general and cut /wp from WordPress URL.
Now I can't access the Dashboard and most of the formatting has disappeared from my pages. If someone can help me reverse my stupidity I'd be grateful.
