Sterling, it's not working for me, either, using the Media Uploader

Sterling,

The plugin isn’t working for me; my site is at http://graphicsolutiongroup.com

Here’s the permalink: : http://graphicsolutiongroup.com/?attachment_id=2187

The svg file shows as a white question mark knocking out of a blue square with a gray border.

Any insight you could provide or anything you could do to help would be most appreciated.
Thank you,
Doug
