After some more debugging I found the problem in my case: I’m using the _s theme which in inc/template-tags.php has these 2 actions:
/**
* Flush out the transients used in hotelflora_categorized_blog.
*/
function _s_category_transient_flusher() {
// Like, beat it. Dig?
delete_transient( 'all_the_cool_cats' );
}
add_action( 'edit_category', '_s_category_transient_flusher' );
add_action( 'save_post', '_s_category_transient_flusher' );
For whatever reason, removing those hooks fixed the problem (which turns out that it was that any and all save_post hooks weren’t being triggered) for me.
Sorry for hijacking your thread @grobear, I hope you don’t mind. It’s just that we have the exact same problem. 🙂
