I have exactly that, all of a sudden half of my thumbnails on my site are the default thumbnail (eventhough they exist in the media/thumbnail/number directory) and when I go to the control panel and click on the Auto-Thumbnailer option it gives me a blank page. I'm running version 1.7.1 on an apache server with php version 4.3.10 on a windows xp professional machine. Anyone got any direction? I been all over this site and can't figure it out. Thanks in advance.
