Greetings,

My set up:

CCK 6.x-2.5
ImageField 6.x-3.1
FileField 6.x-3.1
File system: public
Files set to 775
tmp set to 777

This is on a site that I recently upgraded to Drupal 6.

When I go to remove an existing image, I immediately get this error:

An unrecoverable error occurred. This form was missing from the server cache. Try reloading the page and submitting again.

All of the other threads and issues reporting this error have been fixed without fixing my issue. And it seems to be unrelated to other occurrences of this issue.

Thanks for any help!

Please refer to other issues regarding this problem most of the time this is caused by incorrect configuration of MemCache or Cache Router modules. The error is 100% accurate, the form is missing from the server cache (typically the cache_form table). This means that pretty much all AJAX on your site is likely broken if Drupal is not storing form caches correctly.
