What server OS are you running on? If it's Windows, it's likely
that PmWiki is unable to find the 'diff3' program that is needed to
perform the merge. I thought that I had written PmWiki to be able
to handle the case where merge wasn't available in the OS, but I don't
have an easy way to test this (all of my servers are unix-based).
