For some reason when there's an IFRAME on the page (specifically tested this on the community_topics_list page, i.e. the community page) , the recent activity section is not being displayed - just a blank section.
I confirmed that when I remove the IFRAME the section is displayed again. The IFRAMtE can be anything - even a blank one would trigger this behavior. The one I'm using is a productboard plugin.
Any suggestion to get around this? Thanks for the assistance.
