After the switch to a secured domain (from http -> https), landing pages display both a broken format and mixed content warnings.
Step 1: Open up Landing page with non secure warning sign
Step 2: On Google Chrome right click on the page that is displaying the warning and select "Inspect." On Mozilla Firefox it's called "Inspect Element." Look for any "Mixed Content" warnings.
Step 3: Find and address the links that are referenced in the error messages
**If the link that is unsecure is a custom CSS file, these files will need to be moved and hosted in a secure location so that the links are loaded over https.
