Do not forget to turn off content cache for these two modules. You can do this from Pavilion CP > Theme Settings > System > Cache.
2) About the Sales Motivator: you need to enable Load colorbox.js and Load jquery migrate from Pavilion CP > Theme Settings > System > Compatibility.
We’ve also tried to run the Sales Motivator on the default theme and encountered the same problems as you with Pavilion: the module appears, but the SHARE button is inactive. Maybe there are some specific settings that we miss to apply.
