Landing pages rendering broken?

[Angie_Lin]

All of our landing pages render fine within the Marketo editor, but when viewing the approved pages or preview links, they render as if without a stylesheet. This happens for any and all landing pages. I've attached screenshots of an example of the same page rendering correctly in the editor and wonky in a preview link. Has this happened to anyone else?

The reason is almost certainly because you're not loading the CSS over SSL (while the main document is secure). Same question + answer somebody else had within the last few days. 

You'll see a quite blatant error in your F12 Console, remember to look there first.

Also, Angie, the Munchkin config is incorrect on your Marketo LP domain, which will cause you to lose tracking.

This is because your domain is directly under the 2-letter TLD .co. See here: https://blog.teknkl.com/munchkin-2-letter-tlds-broken/

Possible reason is due to SSL. As some of your assets files like css / js are on http and HTML on https or vice versa.

It would be great if you can share one LP link. So we can debug here.

That's in my response above, yes. Not just possible, it's almost certainly the cause.

Not vice versa. Mixed content only applies if the main document is secure and the subsidiary assets are insecure. If the main document is insecure the security/insecurity of other assets is irrelevant, because the entire response could be intercepted and modified.

OK, We're having the same exact issue. However, these pages were rendering fine 4 days ago. How does this change and how can I fix it?

What's a sample URL?
