ImageCache not working in Drupal

For some reason the ImageCache module doesn't work.

Drupal just doesn't generate the ImageCache subfolders and image files.

The user www-data is the owner of the folder imagecache, I also have set 777 permissions, just开发者_如何学Python to be sure that it is not an issue.

The point is that ImageCache was working on the previous server. Is maybe a server configuration issue?

Have you enabled the ImageAPI GD2 module? Imagecache wont work without it (unless you're using imagemagick). Also look at your drupal status report (/admin/reports/status) and recent log messages (/admin/reports/dblog ) -- any recent errors/setup issues related to Imagecache may be mentioned there.
