I run your software on an IIS under W2012R2 Server. The development is made using Visual Studio 2013.
When I test the page, I can see the file content right using IE11, however, when I see the page already in production the popup window opens but no content is shown, only a small black square in the left upper corner. The same behaviour that posted the user who opened this post. With Chrome everything runs ok but, unfortunately, the IE11 is a requirement. Can you help me?
Thanks in advance,
