I just got a new theme and am trying to regenerate thumbnails. I’m having trouble though. I tried using the AJAX Thumbnail Rebuilder but for 5 hours it just said reading attachments. Then I tried the normal rebuilder but the vast majority of images came back as undefined.
Any ideas?

i have only had to do this on a couple of occasions, but each time i have used this regenerate thumbnails plugin on each occasion with a 100% success rate, however (as you will expect it did take quite a bit of time as i had over a 1000 images that it had to wade its way through on each occasion.
