First, I'd like to thank the author of this plugin for doing an excellent job making this one and also for the great tips on the FAQs page of your plugin. I was able to figure out and resolve most of the problems in my site except for one.
This is the webpage that I am trying to completely secure: https://3icon.com/forum-3
It keeps on saying that the page is displaying an insecure content. I honestly don't know how to fix this one =/ I am using simple press plugin to create the forum. I don't know where to go and what to change for this one.
