To get separate tags of Musk and AI, your YAML should be:
tags: [musk, ai]
and not
tags: [“musk, ai”]
This makes me wonder if you have other errors in your YAMLs that’s triggering the problem.
Sorry for not being clear…
The ‘original’ .md file from the latest Typora crashed the CMS
This version you see now is functioning fine… and the frontmatter was copied from a previous post…
Hope that makes sense…
But yes - probably taking out the “” would be better…
Thanx Thom
I think 
it was a mistake I made…
Typora is fine…
I think I messed up the ‘old’ way of manual posting…
I got used to Claude posting the CMS and auto completing the frontmatter fields… etc
