HTTPS Lock not showing on Chrome

Hi,

I have 2 issues:

1. Calling Element.createShadowRoot() for an element which already hosts a shadow root is deprecated. See https://www.chromestatus.com/features/4668884095336448 for more details.
M9bPKixNLarUMYYydHMz04sSS1L1cjPzdAz0U_PS8nNS9LOK9RPLMhN1k_NzCxJLAA.js:4 JQMIGRATE: Migrate is installed, version 1.4.1

2. (index):159 Mixed Content: The page at ‘https://carnivalwiz.com.sg/’ was loaded over HTTPS, but requested an insecure image ‘http://carnivalwiz.com.sg/wp-content/uploads/2016/04/Carnival-Wiz-Website-Logo.png’. This content should also be served over HTTPS.

Please advise. Thank you.
