Hi,

I am encountering this error when trying to upload images using the javascript upload button when creating nodes:
"An unrecoverable error occurred. This form was missing from the server cache. Try reloading the page and submitting again"

This form was working before but now it is not anymore.

Has anyone experienced this? What is the source of this problem? Where do I start to look when trying to fix this problem?

Thanks

btw, my setup is the following:

Drupal 6.15
Filefield 6.x-3.2
CCK 6.x-2.x-dev
Apache 2
Mysql 5
PHP 5

Thanks for any info on the problem!

The problem is exactly what FileField is reporting. Each time a form is viewed, the current state of the form is put into the cache_form table. After 6 hours this cache is deleted if no activity happens on the form, or if you clear your Drupal caches. FileField needs to load this cache to add another field or upload a file. If the cache is missing then it can't do anything.

ok - in my case it seems to be related to memcached - because I had just made a reboot of the server just before the problem was encountered - and upon further investigation, memcached servers were not properly started after the reboot.

fixed memcached - retested uploading an image - now image upload was successful.

thanks for the info.
