If you activate the SSL certificate and not all content supports SSL encryption, a warning message appears in your visitors' browser.
Use protocol-neutral (//) links to include content (e.g. images, scripts, etc.) that does not support the HTTPS protocol (encryption).
If you use your own HTML code in the Widget / HTML element or in the head tag, check whether it contains links to external websites.
To support SSL encryption, these links must be protocol neutral. Therefore define these links e.g. in the format //1and1.co.uk instead of http://1and1.co.uk.
