So I figured out the problem…

Apparently, the wordpress theme I use for the website is conflicting with the new version of wordpress, and that’s why the comments section of the more recent posts is returning an error 500 message.
What this means is that I now need to hunt down a new theme for the blog… God damn it…
If anyone has suggestions for themes that make any sense, they can let me know. I’m actually not too unhappy with this basic one here, but I may decide to commission an artist to give it a header, at least.
