When I installed Moodle I had not correctly formed my certificate for HTTPS, and so Moodle reported that my site was unsecure (no HTTPS being used).
I have since forced HTTPS and it is now working but the themes aren't working and I am being told that the following won't work until I upgrade them to reference HTTPS:
http://MY_SITE/theme/image.php/fordson/theme/1631567586/favicon
http://MY_SITE/theme/yui_combo.php?rollup/3.17.2/yui-moodlesimple-min.css
<script src="http://MY_SITE/lib/javascript.php/1631561463/lib/babel-polyfill/polyfill.min.js"></script>
<script src="http://MY_SITE/lib/javascript.php/1631561463/lib/polyfills/polyfill.js"></script>
<script src="http://MY_SITE/theme/yui_combo.php?rollup/3.17.2/yui-moodlesimple-min.js"></script><script src="http://www.garynewport.com/theme/jquery.php/core/jquery-3.5.1.min.js"></script>
<script src="http://MY_SITE/lib/javascript.php/1631561463/lib/javascript-static.js"></script>
Where do I go to in order to upgrade these references within Moodle?
