Have you just created your site and notice that you’re getting an SSL error in your browser? So did I and these are the steps I took to correct the problem. The plugin that I have used and had good results is the SSL Insecure Content Fixer plugin.
“Parts of this page are not secure (such as images)”
Once you have downloaded it, head over to the settings section and change the default setting.
Head back to your homepage and hit the refresh button you should see the green lock showing your site is secure. (Images below for help)
When the plugin is installed the default setting is set to Simple, change it to Content to fix the issues on the front end.
