Wiki problem: "HTTP Error 500 (Internal Server Error)"

[Indirik]

OK, I think we're getting closer.

It appears that any template that uses the parser functions such as {{#if: }}, and other related functions, is broken. Templates such as "Infobox CharData" and "HadezCharData" are broken as well.

I'm fairly certain that we need to install/update this extension, which adds support for these conditional functions:

Enabled. Solves the problem for that family, but not the other, which is a different issue, see further above.

This is now all working again.
