When I was on the 5.1.9.1 update, I had the issue where the Featured Content slider would show on single category pages. Using 5.1.8.5 I do not have that problem.
I then realized that some of my events were showing extra meta information, specifically author information and comments, even though I had specifically turned off comments in the EM settings and set the events to behave like pages (My theme is set to NOT show author information in any of the pages on my site, only in posts).
I thought it was a 5.1.9.1 issue but it turned out to be a JetPack issue, specifically the "Share This" option. After disabling that feature completely, the comments section no longer shows in those events, although the author information still does.
I can live with that if I have to, but does anyone know of another way I could turn off author information in the event posts without having to turn the feature off for ALL posts?
