Flavicon, icons, safari svg issue

Hi everyone,

I have an issue with the flavicons, icons and safari svg not showing up in browser tabs.

I have look within the browser and issues flagged and it says that my site is secure by https:// but these files are not.

As a solution I added them remotely to my project file referencing a URL with https:// but the issue still remains.

I then looked at the php file of my home page and saw that it had automatically made these links http:// again and amended them manually but still no luck!

Has anyone come across this and found any solution?

Thanks for your help!
