Problems after implementing HTTPS

Yesterday TMD implemented https on my website.

Result : all the links to modules and photos are broken.

According to TMD :

The URLs that are loading the information from certain modules are getting an error 404 Not Found, due to the fact that they are still loading from an insecure location, instead of the secure HTTPS. Unfortunately, we cannot assist you in fixing those for you, as they are hard-coded in your website's core files.

Additionally, the new .htaccess file is something we have done, in order to properly redirect your website to HTTPS

How can I fix this problem?

OK, this was a TMD problem and I really don't understand their tech support.

First sending me answers like the one above and asking me if I changed something, half an hour later (after they searched some more) they found that they forgot to clear the application's cache on their site.

You need to go edit your /inc/header.inc.php file.

You will see your domain URL about line 3.

$site['url']               = "http://YOURDOMAIN.COM/";

replace to

$site['url']               = "https://YOURDOMAIN.COM/";

Then you will get all your images and stuff back.
