I've configured WordPress to allow subscribers to upload via the Media area on the backend by giving them the 'upload_files' capability. However, when I try to start an upload as a subscriber, the upload freezes at the 'crunching' step. When I check the Library, the file has been added to the site, but the 'crunching' step never proceeds to the image details screen...
Any thoughts on what's wrong? It doesn't seem like a file permissions or a PHP memory issue to me. This is kind of important for the network I'm working on.
Note that everything work perfectly as an administrator.
