Thread:Project:Support desk/Class ParserHooks not found; skipped loading - properties not working

I've been trying to resolve a problem with properties. I've not reinstalled an updated everything I can think of, but the problem remains (I've put my versions below this).

I've looked for these errors and everything I've seen seems to suggest a problem with validator - as you'll have seen, I've downloaded new versions of composer and, thus validator, in case, but it persists.

The error message that I get in the mediawiki debug log is:

Any suggestions of what I should do to resolve this?
