The listing sidebar is in my widget area already. I have three widgets in it. When I select Events from the home page and go to http://derekmccoymusic.com/events/ I see all three widgets in the sidebar which are in the “GD Listing Right Sidebar”.
When I select a link from the CPT Categories widget on the events page the resulting page that comes up is the one that I am having issues with: http://derekmccoymusic.com/events/pistol-hill/?etype=upcoming. There is where I do not see the CPT Categories anymore.
I did as you suggested even though I did not understand the logic. I added a top section and this did not help. I still don’t see the CPT Categories widget on any of the results from the widget on the events page. And I don’t want anything in the top or bottom section. So, I’m still in the same situation.
This creates a problem because when someone selects something from CPT Categories widget on the events page the resulting page not having the CPT Categories to choose from doesn’t enable the visitor to easily understand how to go back and/or select a different category.
When I use the widget Popular Post Category in the listing sidebar everything works as it should. However, the problem with this widget is that it doesn’t display properly on phones if the category name is too long (see attached). I guess I’ll just live with this widget instead and just shorten the name…
