I’m getting a mixed content problem with my site homepage. It seems related to the theme demo content I used to build the site:
“A file with an insecure url of “https://www.8theme.com/demo/xstore/landing-watch/wp-content/uploads/sites/19/2016/09/image-2.jpg?id=43″ was loaded on line: 1102 of https://1stgraphene.com/.
This URL will need to be updated to use a secure URL for your padlock to return. ”
How can I safely remove the insecure content?
