@prashant280920 check the contacts page
On some pages, this error actually comes

you just need to convert http to https

and remember while working, do it on another branch with currently updated master

@Signior-X, I tried this, and now on contacts page I can see only two errors. So at present there are only two of them. Right?

@LalitNM it will be awesome if you create a PR. So, your screenshot do solve a part of this issue.
At present, there are three errors. I think instead of removing, making the http to https will solve the error.
