Hello, I am implementing uploadify in my rails apps and I currently have a similar problem as described in this old post (http://www.ruby-forum.com/topic/156139) with the same error message. This message occurs only when I try to upload a file when on a Mac and the apps being deploued on my hoster environment (Apache+fastCGI). Uploading from a windows environment works fine Here is my configuration: Development: Mac OS X.6, with rails 2.1.2, uploadify 2.1.4, webrick --> everything is ok Integration: Mac OS X.6 on +flash 10 the client side and, rails 2.1.2+ Apache 2.2+fastCGI on the server side I get this message only if I try to upload a file from a Mac, on a windows platform it work ok. Any idea on the solution? Thanks in advance Nicolas -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
