HELP: changed root directory and now no css is applied

Please help!!!!

I redirect baptistlifeonline.org to baptistlife.bcmd.org Drupal is installed on this site.

I installed wordpress on baptistlife.bcmd.org/wordpress. After the site was set up, I changed the root directory through dreamhost for baptistlife.bcmd.org to /wordpress. Everything was fine, except that baptistlifeonline.org wouldn’t point to the new directory.

I went into dreamhost and altered the root directory for baptistlifeonline.org to point to the same /wordpress directory. It didn’t work and now both sites point to a site with no css applied AND I get a 500 error when I try to access the wp-admin page. I think I broke it. What do I do?!?!
