Hi.

8: I have access to the Localhost.
9: Of course, I don't have access to phpMyadmin.
10: Actually I can view the phpMyadmin's log-in page slowly, but I can't log in. There are some messages you may be interested in (I'm a foreigner, so translate these characters in English, sorry for that):
The HTTPS setting between the server and the client does not match. Continued use can cause phpMyAdmin to go wrong. Please correct the HTTPS settings set by the server.
Failed to set session cookie. Maybe you are using HTTP instead of HTTPS to access phpMyAdmin.
11: I am using Avast Free Antivirus.
12: C:\wamp\
13: I haven't done anything, so maybe I don't have any virtual host.

Thanks.
