Hi, I'm testing my web in a windows Server, and in IE Pie don't work, I see in common issues that it's probably a problem of the Content-Type. There are another way to fix this, with an update of PIE? Or the one way is modify the Content-type in the Server?

thanks!

There is no way to get around the content-type requirement in PIE; it is enforced by IE before it even loads PIE. You must make sure it is served correctly.
