That's strange when you say that: http://www.novarelle.com/wp/wp-admin
is working fine,
It isn't working fine, as I mentioned above:
"this: //www.novarelle.com/wp/wp-admin
- redirects to -
//www.novarelle.com/blog/wp-login.php "
Yes there are 2 sub-directories, but they are two un-related setups and they are both using different databases.
Then you should be asking yourself why accessing the /wp-admin directory on one, redirects to the login page on the other. That should not be happening, agreed?
I don't think my "access denied" issue is due to the fact that I have more than one Worpress installations.
I agree with you completely. I've done the same thing many times with great success. However, if you botched something up with your URL's (as the re-direct from one site to the other suggests), then the results become less predictable.
I was finally able to access the login page, but only after coming though a proxy service.
I think your ip is most like being blocked for reasons unrelated to your WordPress sites. It might even be on a blacklist somewhere. It happens.
