I have greensql-fw-1.2.2-17.1 installed on a Red Hat Enterprise Linux Server release 5.5 . GreenSQL is running and when tested from the command line and another app, it's doing what it's supposed to do.
The problem is when trying to access the login.php .
/var/www/greensql -> /usr/share/greensql-fw/
When going to http://127.0.0.1/greensql it redirects to http://127.0.0.1/greensql/login.php and shows a blank page.
I have tried this on two separate servers with the same result. I also put a phpinfo.php page in the greensql directory and that works fine.

greensql 8409 0.0 0.0 36084 2088 ? Ss May24 0:00 greensql-fw -p /etc/greensql/
mysql is running.
PHP Version 5.1.6

I have run out of ideas.
