SSL Issue with my Wordpress Website - Need Help Please

my website (HostingHosted.com) is giving SSL issue, as few years back it was on hTTPS now its removed i..e now only http - but whenever someone comes on my website, it gives kind of " warning message - Not secure" -

I tried to install different wordpress plugins such as https://wordpress.org/plugins/ssl-insecure-content-fixer/installation/ but nothing seemed work, can someone please help.

Your SSL expired on 21 dec 16 hence this "not secure" warning.

I can also see bunch of resources loaded over http protocol. You need to change links of all those resources to "https" manually .

In "chrome" you can right click on the page and click on "INSPECT" then move on to the "CONSOLE" tab to see all the resources which needs to be edited.
