Iframe opened by OpenURL stopped working
Hi,
I invoke an iframe into a HTML snippet in my Page using openURL. I created this workflow a few hours ago, it worked for a time and now is giving me this error:

Also, when I invoke the same report within an iframe, it works. I use the following code:
Please help!
Also, I have a question: is it possible to filter a report by filtering a multi-select lookup with ID?

Thanks!
