I have an existing site built in wordpress and I've created a subdomain where i wish to place a second installation of wordpress.
I've set the subdomain up via cpanel and installed wordpress via fantastico
Although I can see the wordpress installation, I can't log in to the admin panel. There is no 'wrong password' error message.
I've cleaned the cache.
The main site does have a redirect on it to convert non-www URL's to www URL's. Not sure if that will affect it.
