This was discussed in a old post, there were no solutions.
This is about a year later, wonder if anyone has a clue.
I generated a reply to the old post but did not receive a response.
I have 1.3.8a installed.
We host the store internally on a windows server - IIS7.
The store has functioned well for almost a year.
When I set Configuration-Website-Maintenance=true and filename=down_for_maintenance, the result is "Service is unavailable."
I have a local version using WAMP.
The down for maintenance page comes up fine.
The code is exactly the same except of course my configs which point to a different directory and base URL.
I was hoping that this would fail on my local version because I have a debugger, but it doesn't.
I experimented by changing the Website-Maintenance filename to Privacy and the privacy page comes up fine on my problem IIS7 server.
So once again, here is the situation.
Same code, both environments except of course include\configure.php and admin\configure.php
Configuration-Website-Maintenance=true and filename=down_for_maintenance
WAMP environment -- Down for Maintenance Page - Yea!!!!!
IIS7 environment -- White Page - 'Service is unavailable.' Boo!!!
Anyone got a clue?
Since the server is the responsibility of our IT group, solutions like don't use IIS 7 won't help.
I'm hoping that someone had a similar problem and solved it on IIS7.
