I have a category that I am displaying on my site with the auto-generated thumbnails. Most files are never changed. However, I have just updated some files but cannot seem to get the thumbnail to update.
Outside of deleting Post and starting completely over, is there a way I can have the thumbnails match the new instance of the PDF they’re linking to?
I have even overwritten the png file directly on the server, and manually cleared the cache on the Settings page, and still the original image persists. Maybe I’m overlooking something, but I’ve tried everything I can think to try.
Thank you for your help!
