No, but I decided to set up the plugin on a live server to rule out anything with my local environment. Now I’m getting different log results but still having trouble – I entered the same expiration settings (delete entries older than 4 months, every 1 hour), and according to the log the plugin ran correctly, but none of my entries older than 4 months were actually deleted. The page numbers in the log also do not match the number of pages displayed in the Gravity Forms entries interface/pagination. Not sure if these are supposed to match, but according to the log form #1 has 27 pages, and in my GF interface it has 47 pages of entries.
Here’s the log:

Thanks again for any help!
