hi,

i use attachment_fu in a rails app called community_engine.

On my MacBook everything works fine with image uploading and thumbnail creation. After porting the application to my Provider in a centos environment, it only handles the original file (upload, copy to dir, enter a record in the table "photos")

The expected thumbnail generation is skipped - silently. So i searched the web, found similar problems - with no answers... Debugging shows that no error happens. The callbacks are simply not called. Thats all. And it is impossible to find out why.

After several hours of hunting the bug i hope the pros here can help me. I assume the reason is something like "version 1.5 of X does not work with version 2.x of Y, when using Z in Version 3.1"

So here is my Setup:

ruby 1.8.5 (2006-08-25) [x86_64-linux] rails 2.1.1 ImageMagick-6.4.1-10

OS: CentOS 5 mit Plesk 8.3 (64 Bit)

installed gems:

actionmailer (2.1.1) actionpack (2.1.1) activerecord (2.1.1) activeresource (2.1.1) activesupport (2.1.1) cgi_multipart_eof_fix (2.5.0) daemons (1.0.10) fastthread (1.0.1) gem_plugin (0.2.3) haml (2.0.3) hpricot (0.6.161) htmlentities (4.0.0) mongrel (1.1.5) mongrel_cluster (1.0.5) mysql (2.7) rails (2.1.1) rake (0.8.1) rdoc (2.1.0) RedCloth (4.0.3) rmagick (2.6.0, 2.5.2)

Delegates are:

DELEGATES bzlib fontconfig freetype gs jpeg lcms png tiff x11 xml wmf zlib

Perhaps someone can check if there are any incompatibilties or give me a hint, how to find out what's going wrong.

Your help is much appreciated.

Thanks

martin
