So I thought, alright, I'll give XC5 a go, having not tried it in years... surely it works ok by now.
Fresh v5.4.1.26 install ... It required a MariaDB upgrade .. ok no problem.
Install went fine, it indicated I should update the apps, so I did.
Next thing, 502 bad gateway.
Thought, ok maybe I need to redeploy the store, so I did.
502 bad gateway.
Maybe an integrity check will fix?

Left with a dud store, with seemingly no way to fix... admin menu buttons don't work either... grrreat.
Edit, then half an hour later, with no intervention by myself, the store starts working again... hmmmm
Theming-wise, doesn't seem to be much choice, aside from changing logo and CSS overrides.
Some admin functions don't seem to work 100% in Firefox...
And don't call me Shirley.
