"page not found" when trying to add image node to drupal 6

I get this error recently, after I migrated my site to a new server and upgraded from drupal 6.20 to 6.22. Whenever I try to add an image node (or my other custom-defined node in which there is an image upload field) I end up with a "page not found" page. 开发者_运维知识库Previously created nodes are displayed without any issue.

All the installed modules are exactly as before and are updated to their latest version. I really appreciate your hints.

Ok, I found the culprit in the status report:

The sites/all/modules/image/image.imagemagick.inc file must be copied to includes in order for the ImageMagick image toolkit to function

Copying the file solved the issue. Silly me!
