I have both WordPress MS & domain mapping working beautifully, and I am a happy bunny...
EXCEPT when I try to upload an image with the Flash Uploader, I get a bright red "Security error." come up. If I use the Browser Uploader, I don't get an error message, it just doesn't work.
I'm sure this has to do with cross-domain security. Does anyone know what the fix is? Something to do with the .htaccess rules?
btw I'm hosting on DreamHost VPS.
