For some reason, my gallery has errors. When you go to the main page, you’ll see broken thumbnails. Rebuilding the thumbnails results in debug output, that show messages about existings files and so on. I know they exist, but I want to recreate them.
I Googled around, and found similar problems, most of them related to incorrect directory security settings, or to memory problems. But the machine has not changed and the pictures now with broken thumbnails had thumbnails before. The directory security has not changed either. So I guess I will need to dig in… 🙁
