There seems to be a strange conflict when a WordPress installation has "The Event Calendar" and "Gallery (by BestWebSoft)" installed at the same time. In role scoper, with the event calendar installed, the events, venues and categories all show up in role scoper. As soon as you install the Gallery plugin, the event related post types do not show up in role scoper anymore. I feel like this may happen in several other plugins as well.
Any advice on how to fix this?
