I am new to wordpress and have made a partial mess. My website is (or maybe was) on karlmark.se and the wordpressversion I want to replace it with is on karlmark.se/ny. When I was playing around with getting the old one to be replaced with the new one I changed the address in the adminsection from /karlmark.se/ny/wp-admin to http://www.karlmark.se/wp-admin. That seems to have been a stupid move because now I get an ugly site and can´t reach my admin section at all. How can I solve this wonderful little mess?
