@jeffca, @enlightenmental1: first of all check that your .htaccess rewrite is being amended after you change the settings in WP. If it isn’t, it’s a permissions problem.

Are you both on godaddy? If you are on godaddy, I believe they only process .htaccess files for updates once an hour. Change the permalink setting in WP; check that WP has rewritten the .htaccess; then go outside and wait an hour. Come back, and then test.

Oh, and if you aren’t on godaddy and the above doesn’t work (wait at least 60 minutes), try putting Options -MultiViews at the very top of the .htaccess.
