I'm trying to run zenphoto 18.104.22.168 on my hosted server and I'm facing lots of issue with respect to all admin process which are supposed to generate thumbnails and populate cache (admin action like add/remove an album works ok)
I've got 403 error any time I want to generate thumbnails which is in line with a lot of posts in both french and english about permissions issue (depending on your host provider, OVH in this case). Workaround seems to be to manually set to 755/644 for folders/files after the setup. This is indeed mandatory for me to be able to run zenphoto, but not good enough for these cache/thumbnails admin processes to work. Cache is always empty, thumbnails are either pretendingly generated when it's run from the general overview page (just question marks are generated, cache empty) or not generated at all when call for a single album/image (403 error).
Thanks a lot for your support.
