The API connection was the issue, so the Eventbrite info is now showing up on new posts.
As for the other issue, I am using the sidebar widget on our homepage (www.rentonrfa.com). As you can see, the events marked as “featured events” in your tool have a baby blue background. That is not any setting in our theme, or brand, nor do I see any place in your UI to specify this color. I have no idea where it came from, but I need to be able to change it.
I’m just looking for the snippet of CSS that allows us to change the featured event background color on the sidebar widget. Just the attribute name would help and I can add the CSS myself – I’m just not having any luck properly referencing it.
