I recently adopted a new theme on my wordpress.com blog (http://akisaokay.wordpress.com) to allow for multiple post formats, and now would like only for Standard format posts to be included in my Recent Posts sidebar widget. While there's no format selection option, It looks like the widget allows for exclusion based on category, so I created a category for non-Standard posts ("Brief") and set the widget to hide posts in that category. And yet, they persist in showing up. When I tried the opposite approach and set it to show posts in every other category, the widget disappeared from the sidebar altogether.
What am I missing here? Any other suggestions?
The blog I need help with is akisaokay.wordpress.com.
