Post showing up locally, but not online

Can’t work out why my latest blog post isn’t showing up on my webpage after push.

It shows up locally on jekyll serve - can’t work out what the problem is.

My website is here, and the markdown for the post in question is here, along with the rest of the Jekyll files.

Any advice?

many thanks,

baha ok I worked it out. some of my posts where dated to the year 2202 instead of 2022.

I’ll leave my post up as a reminder to be vigilant wrt dates. best wishes
