Problems generating Diffs

[cmiles74]

I have DekiWiki running on FreeBSD and I'm getting an error when I try to view the difference between page revisions. Aside from this, everything is working great.

It looks like it's trying to write to files in the Apache user's home directory. Apache doesn't have a home directory, so it can't write the files. Is there someplace where I can change this?

Any help would be greatly appreciated. :)

Thank you,

Here's the output I get onscreen when I try to compare page versions:
