Nick,
I rarely ever add, change, or modify my theme, widgets, etc. I know your plugin was working correctly a few months ago and now, I, too, am not getting event description popups when I click on the dot in the sidebar calendar widget. I haven’t updated the theme in a while so it can’t be that. Below is my system report:
