We have several clients who experience failed uploads using the Flash uploader. All they get is a http-error (500,as I recall) when they upload. I have tried editing the htaccess and ngg-config to no avail. FWIW as far as I can see, this is especially a problem on multisite. We're not running Contact Form 7. Any clues on what may be the issue at hand, and if Photocrati provides support for this software? Thanks in advance.
