This article provides you with information on how to resolve a mixed content SSL error on your website.
When your SSL certificate fails to encrypt all of the elements on a page (for example: forms, textboxes, images,URL’s etc.), customers receive an “parts of this page is not secure such as images” message in their internet browser.
That error will show up if parts of the website are referencing images and resources that are using a standard URL hosted elsewhere. So if you have an image that is being pulled from http://example.com/imagehere.jpg, you will need to update the link to https://example.com/imagehere.jpg to show up as secured.
Fixing Mixed Content Error in WordPress
First thing you need to do is install and activate the SSL Insecure Content Fixer plugin.
Upon activation, you need to visit Settings » SSL Insecure Content page to configure the plugin settings.
