My site is set up to run as https and seems to running properly. But when I do an SSL site diagnostic. I am getting SSL mixed content errors. Here is an example: A style-sheet with an insecure url of "http://tri-learning.com/moodle/theme/yui_combo.php?rollup/3.17.2/yui-moodlesimple-min.css" was loaded from https://tri-learning.com/moodle/admin/index.php.
If I read this error message correctly, it is saying that something in the index.php is requesting "http://tri-learning...." instead of "https://tri-learning..." I have looked at the coding inside the index.php file that might be causing this, but have not found it.
Anyone have a guess? Much appreciated.
