I deleted the subdomain, SQL database, and this install of WP. Recreated the subdomain, SQL database, and copied a fresh WP install, changing wp-config.php to the SQL settings. It still does this. On our main page, stlcoplxa.com, it works fine, but members.stlcoplxa.com doesn’t seem to like logging in or loading correctly. Also, i don’t think the period should be an issue; I tried it with the main page and things like google, yahoo, msn, etc. and they all worked fine.
