Can other modules be causing a problem?
That's the only difference between my test site & this live site.
A blank site means you have a PHP error somewhere. Make certain that the code is exact for that file from site to site.

The best way to do this is to perform a "winmerge" comparison on the two files. This will show you where there are any differences between the two and likely lead you to your problem.

The other thing you can do is to check your error log file (generated in the cache directory) for the root of the problem (on the live site.) As long as you have that turned on (by default in 1.3.9 + but needs to be added in 1.3.8 and under) you'll get the exact spot that the problem is occurring.

Let me know if that helps.
