Why am I getting an error on secure / HTTPS pages on my site?

If DTM works as expected on non-secure pages, but shows errors on secure pages, then the issue is likely related to the way the code is placed on the site. Locate the DTM code snippet on the client's site by opening their page source and typing ‘ctrl/command + F’ and searching for ‘satellite’. If the code includes ‘http://’ or 'https://', then this is the issue. The code should be written without any http / https to accommodate secure and nonsecure pages – like this:
