I was messing around with the root .htaccess file to redirect urls into the /wordpress/ directory. I then found the setting to specify the address of the blog, so I changed that, too. Then things weren't working quite right, so I took the 301 redirect code out of the root .htaccess and the site is now completely buggered.
Where can I go change the blog address setting back to /wordpress? None of the admin pages will load and anything else gives me either the WP 404 or a default 404. Help! (I've cleared the WP stuff from the root .htaccess.)
