My search-fu can't seem to find a solution.
I'm trying to upgrade my Mediawiki installation from 1.39.3 to 1.42.3. Probably shouldn't matter but I'm using the official container.
I've run the installer/upgrader and the database was updated and whatnot.
I've upgraded all the skins and templates to the appropriate versions for 1.42 but I can't seem to get around an issue with TemplateStyles.
I get a fatal error:
https://fxide.io/TemplateStyles_mediawiki_error.txt
Disabling the extension makes the site work correctly but with the <templatestyles blah blah> stuff inline as expected.
I thought it might be related to jumping too many versions?
Or is it something else?
I'm testing the upgrade on a VM so it's not a big deal to tear it all down and add an intermediate upgrade step but if I can I'd like to avoid that (time constrained).
Docs say LTS to LTS is ok or did I misread?
Did I miss a "new and exciting" configuration step?
Missing something obvious?
Anyone have any insights?
Thanks a bunch!
