The infamous "securitySandboxError"

I do FileReference uploads regularly and have heard other people complain about this but have never gotten it myself. I do not understnad why i am getting it now.

I can test the file upload from the SWF locally(with php online) and it works fine. However when i upload the SWF and then try running it from the server, it gives me the securitySandboxError.

I have tried changing from “access local files only” to “access network only” in the publish settings. But other than that i can’t figure it out.

Theres no point in setting up a cross-domain policy as well… it doesn’t work on the same domain, but somehow works when it is on another domain(my computer).

If anybody has any ideas, i’d love to hear them. I know this is a bit advanced but i’m sure somebody out there knows, Sen? Canadian?
