I have almost completed a manual install.
Having filled in the page at wp-admin/install.php , and receiving the automatically generated password, I was brought to wp-login.php.
However, having entered my username and password and clicked log in, the page went blank. Manually going to any page such as wp-admin/index.php (the dashboard) just displays  on a blank page.
The site is up, displaying the default page with the test post and comment, with my blog name at the top, but I can't and have never been able to log in. I am definitely using the correct password, as when I try a wrong password, the login page throws up an error as it should. Therefore, the password is accepted, but I can't get any further.
How can I solve this?
I know that another poster had a similar problem and posted at this thread: http://wordpress.org/support/topic/194115
If the original poster Pecharroman, or the moderator samboll reads this, can you please tell me how the problem was fixed.
