When I installed Blox and added Add-on to my system I notice the content from UniteCMS was not secured or coming from a non-https server.  And it does create a Mixed Content Error in Chrome on the front end.  Can you please update your system. 

And to make sure I got this correct any addon that states or have Web on it have files that stays on UnitCMS Server so when you use that Addon certain files will need to be pulled from your server.  And this is what causing the Mixed Content Error in Chrome.

Now to solve the Mixed Content Error isn't it best to let people download the Addon Library Addons and then installed them on the their server so nothing needs to be pulled from UniteCMS system at all or you can update your system. Even this website is not secured and people information can be hacked by the guy in the middle of you and your users.  Your support system is secured but not the website where people sign up or purchase BLOX and Add-on Library.  

If I have this wrong please explain... 

Thanks 

Can you tell me if this is still an issue?

Many thanks

Max in order to get around the mix content error in Chrome  or Firefox you need to remove the http or https from the link like so:

Change from:

http:// www.unitecme.com/blox/whateverfile.php

https:// www.unitecme.com/blox/whateverfile.php

http:// unitecme.com/blox/whateverfile.php

https:// unitecme.com/blox/whateverfile.php

To this:

//unitecme.com/blox/whateverfile.php

This will solve the Mix Content Error no matter what a person has http or https.
