Images from are coming from http instead of https

Hi,

My website is on https(SSL enabled) all pages are working fine on https but few images which are coming in the background from css generated dynamically by s2member plugin are still on http.

Below are the list of images which are on “http”

Check that you are enforcing SSL on your WordPress site. The content_url defaults to HTTP if you are not enforcing SSL.
