I have have the Version 3.0.4 + PHP Version 5.2.17 + WordPress 3.3.2.
When I add a new article and click on your IM logo a popup error show:
Internal Server Error and the same error when I try to edit an image.

Other problem:
I put this line in article with correct ID >[ims-gallery id=”aaa”]
but don’t show nothing gallery

I think that this last problem is linked to the first.
Thanks for your support
