I have recently tried to install WP several times with the same results. Once the install is completed, WP shows the page with the admin login name and auto generated password. I click on the link to login, put admin in for the username, add the autogenerated password. When I click to login, I am automatically redirected to my websites home page. For example, the WP files are installed in the http://www.mysite.com/blog directory. When I try to login, I get redirected to the home page at http://www.mysite.com.
Any insight would be greatly appreciated.
