HCL (Help Center Live) - Page contains both secure and nonsecure items

Installed Help Center Live on Zen Cart v1. 37.

When entering the checkout, i. e. switching to SSL, the above warning displays. It is due to the status icons.

I saw the following thread in another forum:

but could not understand which files to edit, and it also looks rather dated.

Any ideas. . . ?

When IE asks you "Do you want to load the insecure elements?" (or similar wording)

Choose "NO"

... then look at the page. You may see what is causing the problem by it NOT being displayed.

Usually, it's a full http:// URL to a resource and because your SSL is kicking in, it must have everything coming in from https://

If there is something (a page element) that is being called via a http:// link (or reference) that part of the page is insecure.

Thanks, but I realise its the image file causing the issue, but because its all coded in Help Center Live it is not easy to work out how to change the URL to https...

i am having the same problem on the hunt for the right php file, let me know if you got it already

Only way i found of fixing it...
go to hcl/config.php
// The URL where HCL is installed
$conf['url'] = 'http://yourdomain.com/hcl';

change to
// The URL where HCL is installed
$conf['url'] = 'https://yourdomain.com/hcl';
