I'm using the editor to set up an iframe from "Keep and Share". The page works OK with chrome and Edge but when I preview the page using CC editor with chrome it hangs and I eventually get a message in a grey box that says cannot find the directory or file"
Page here:

<iframe allowTransparency="true" src="//www.keepandshare.com/calendar16/embed_calendar.php?i=2629904&style=v&fmt=std&startdate=&soffset=0&n=5&h=75&w=280&dbc=&hc=&htc=&tbc=&tbtc=&ltc=&ntc=&mntc=&mnbc=&sr=y&navicon=caret&fsz=12&nav=y&ac=y&sparse=y&lang=&ifr=y&frw=280&frh=450&frs=no" width="280px" height="450px" scrolling="no"></iframe><!-- For help on embedding calendars go to http://developer.keepandshare.com/embed … lendar.php -->
Anybody know what's happening?

Change:
src="//www.keepandshare.com/calendar16/embed_calendar.php?

to:
src="http://www.keepandshare.com/calendar16/embed_calendar.php?

Thanks so much Scott that resolved the issue perfectly.

Now on to something else...
