I have spent several hours trying to solve a problem with filefield and imagefield combined to upload images. I have enabled version 6.x-3.9 of both modules but of course this error message originates from inside filefield.
The image upload works on the install of the site on my PC and most things are the same, eg Drupal version but it doesn't work on the server. phpinfo tells me that post_max_size and upload_max_filesize are both set to 128MB and all other relevant variables appear to be set to relevant values. (on the server)
When I attempt to debug the script I find that the $_POST array in filefield_js() is empty. This is rather unusual. I believe this is generated from ahah.js and have reuploaded all the /misc scripts in case something was corrupted. Is this array empty when there is a filesize problem? Do I have to look further at my server to see what upload configurations are not set in order to solve this? Form_cache appears to be working.
This is an unusual problem and I have not met anything like it in three years of using this module. Any insight would be appreciated.
