I have a multisite install that before today had one subdomain and the main site. Everything worked fine. I added a second subdomain today and the wp-admin area is blank. I can see the site, but cannot access the admin area. The first subdomain works fine and I can access wp-admin on that, but just not on the new subdomain.
I contacted my web hosting provider and they tell me it is not a server side issue and they believe it is likely an .htaccess problem. Have you seen this before? Any thoughts on how to fix this?
Thanks,
Samm
