In my production machine thumbnils arte not getting created

[ramanaveli2i]

Am using attachement_fu, image-magick, r-magick for photo processing.

In my development machine all getting worked correctly.

But in my production machine the thumbnails were not created but the photo object was saved.

When i put the log in the attachemnt_fu plugin(attachment_fu.rb) in after_process_attachment method

the respond_to?(:process_attachment_with_processing) is coming as false

I don't know why. For Further debug i put the log in rmagick_processor.rb in process_attachment_with_processing but its not getting called too.

Please help me out from this problem.

I have changed the production machine last month from that only thumbnails not getting created. Before changing the production machine thumbnails were created correctly.

will i want to reinstall the image-magick and r-magick or give some fix please.
