Good news: I finally got my blog working in part by deleting my _site directory and re-rendering everything. Now, though, a strange issue on my Quarto blog - I can't get the category listing pages to display posts properly.
If anyone thinks they might know why, thanks in advance!! More details in my @Posit forum post :
