URL not working in iFrame

IMHO it is related to http/https protocols because Chrome’s console shows these errors:

Uncaught SecurityError: Failed to read the ‘frame’ property from ‘Window’: Blocked a frame with origin “https://awscmw1a.fwicloud.com” from accessing a frame with origin “https://localhost”. The frame requesting access has a protocol of “https”, the frame being accessed has a protocol of “http”. Protocols must match.

Uncaught SecurityError: Failed to read the ‘frame’ property from ‘Window’: Blocked a frame with origin “https://awscmw1a.fwicloud.com” from accessing a frame with origin “https://localhost”. Protocols, domains, and ports must match.

I’m sorry – I don’t entirely understand your answer. Can you dumb it down a bit for me? This is the actual URL (but same result) – https://awscmw1a.fwicloud.com/cmweb510/?sign=Demo_iPhone_WP&client=npwpsccd

Iframe is embdedded via https secured connection.
And it wants the parent page to have secured connection too.

Change this: https://site.com to this: https://site.com (where site.com is your website with iframe) and see if it helps.
