hey i got blank page too, after upgrade to 1.5
i installed apache and mysql as services.
the status page works fine, and also phpmyadmin.
so i set my document root in apache config file and my index.htm with no php works. but when i try to access my forum (phpbb integramod) I get a blank page. checked the page source and there's nothing. I am using localhost though. 127.0.0.1 don't even work (firefox says cannot find server)
I'll try to go back to 1.4 and see what happens
