@jeffp. Thanks for posting. i would be happy to assist you. Http error 400 is a sort of non-specific error that swfupload gives. I noticed your destination is set to “public_html/plugins/content/easyflashuploader”, which really should not be, and is probably the source of your problems. I am pretty sure that the default settings have destination set to “images”. If you need more direct help, please send me an email to support[at]valorapps[dot]com
