Images Not Created

I’ve been using this (awesome) plugin for over a year.

I hadn’t tried to re-import thumbnails in a while (just because I have forgotten to do so), and when I recently tried, no images were imported.

I get no error. But no images are imported.

All the previous thumbnails still exist, but any additional or changed thumbnails don’t import.

I didn’t know if, perhaps, one of the several WP updates that have occurred since the last plugin update messed something up or ?

Thanks!
