Similar issue.
Running php 5.0.4 and MySQL 4.1.3-beta (which should be fine according to the installation guide, but as divyesh mentioned - the installer itself mentions 4.4 - I haven't the permissions to upgrade but as soon as I do I'll try)
Everything copies over fine, the install page works fine. I input all the data and hit submit and then am faced with the same blank page aforementioned...zip, zilch, nada.
If I try to visit any pages (www.mysite.com/helpdesk/login.php(www.mysite.com/helpdesk/login.php) or even just www.mysite.com/helpdesk(www.mysite.com/helpdesk)) I'm faced with a:
Fatal Error: Contact server administrator
This isn't a problem with the connection to the database, as phpmyadmin verifies that the tables have been created and populated (curiously though, it appears the admin account I created with the install is not there, or I'm just looking in the wrong place).
Some solutions would be great guys!
Edit: The message I get sent to my inbox along with the fatal error is:
Unable to load config info from DB. Get tech support.
