Issue: Template Error after search upgrade (VW disabled)

This is the same issue as reported a while back. Unfortunately it looks like XenForo never fixed their bug. Here is an explanation:
https://www.vaultwiki.org/issues/5958/#issuenote_32704

You might be able to resolve this by clearing XenForo's guest cache, or any other static HTML cache you have. However, it is still possible to receive this error if users are viewing other cached versions of the page.

I haven't seen any further Template errors, so I'm going to assume that this error is probably not a big deal. Interesting that it goes back so long though.

I have received a couple of related / identical template errors:

Assuming these are based on the XenForo bug mentioned above.
