Re: "scroll down" - well don't I feel silly! Thanks!
Now that I unchecked it - do I have to re-create the Landing Pages to get rid of the tags?
Of course, I tested it! That's why I asked the question. The security warnings are still there and I still see favicon references in the source code in the live page. And when I created an LP from scratch - with not edits - just the plain template - the security warnings are there, too, and so are favicon references in the source code.
Page existed before I checked the box:
New page created after:
So just to be sure I'm understanding your blog post correctly. In this case that would mean creating a redirect:
"https://go.netsertive.com/rs/479-FPP-504/images/favicon.ico " [which I have confirmed does not exist - it's just Marketo making it up, as you said]
Is that correct?
I implemented the redirect and I updated the fallback and home pages to https.
I'm still getting the security warnings on the LP's in Firefox - without exception. And with one of them - this one - I get warnings in both Firefox and Chrome:
Any other ideas?
