[Plugin: Advertising Manager] Nothing appears after an ad

Whether it’s a widget in the sidebar, or shortcode to pull ad from within a post, anything after an ad disappears. If it’s in a post, the post content doesn’t show at all, and neither does the ad. Somewhere, a code is broken.

I’m using the latest WP, a brand new install, A brand new StudioPress child theme for Genesis and have previously enjoyed this plugin, but now it’s breaking stuff.
