I've done a great deal of research on how to workaround Wordpress's iframe restrictions and I've been able to get it to work using various plugins with common services (google maps, youtube, etc.). However, all of these methods have not worked for embedding one of my published webApps. My most recent efforts have been using this plugin.
Here is an extremely simple 'Hello World' webApp that I would like to embed: LINK.
I was unable to simply use that URL as the 'src' for the iframe so I embedded the webApp in this google site then viewed the source of that iframe which I found to be:
<iframe src="https://sites.google.com/macros/s/AKfycbyAFo9aWOUw3FxiVZTGad6sgpcIbxZm1g9dS0yujV0tOBAI3582/exec?authuser=0&mid=ACjPJvEpRFnQA1LHa7qtEGta-zgj2r8oi_E2l-BUfSFUNBlxmagk2TXEd6msYIW1i7b4lfPTkEc9dZLm795dplLiaH7LZ3GchmiVtMYyXnBeeGhQ-NfS8a7-2n7NKzqPFibZ1fqr&bc=transparent&f=Georgia,+Times+New+Roman,+serif&tc=%23333333&lc=%230036b3" title="Apps Script Gadget" width="150" height="100" frameborder="0" scrolling="no" id="maestro_frame_1429669030"></iframe>
I then used that iframe code within the plugin's shortcode on the wordpress page and nothing is shown when published. The frame seems to be there but it's completely blank. When I try to view the frame source - it's blank. Please help?
I'm open to other ways to do this. I just need to somehow embed my published GAS webApps.
