Version Diff Not Working...

Permalink
Maybe it's been answered before - but I can't seem to get diff versions working. Python is installed at usr/bin/python, and I've set htmldiff.py to 755.
I can select two versions to compare, but it just comes up a blank screen.
Anyone know any possible solutions?
I'll try doing this on a fresh install...
Can it be caused by a template?

Looks like I just needed to add:
enable_functions = system
to a php.ini in the root of the site... Odd error.
