Stopped working

I have been using your plugin successfully with woo commerce and our Cheope shopping theme without issue. But I seem to be having the same problem as others. I’m not able to add conditions or create a group. In fact clicking the “Support The Author” button on that page doesn’t work. Older sidebars are still working but when I try to create a new I can’t add any conditions.
