Something is not right with your site. Even when I access the site with https:// the following code returns the URL without the https://

How did you enable your SSL? Is this using some sort of cloudflare setup? It seems like Joomla doesn't think that you are on SSL because the url that Joomla returns is without SSL.

This issue does not only happen to Easyblog. All of your other extensions are also having similar issues.
