In your screenshots, the theme icons are not being loaded, they should look like this:

Cropped screenshot using Academi theme with Font Awesome icons highlighted (e.g. telephone, speech bubble)

This may have the same cause, whatever is blocking the icons is also blocking JavaScript calls resulting in the "undefined" message.

The cause could be this:

  1. The Moodle site's URL is HTTP (not HTTPS).
  2. But browsers are loading files using HTTPS (not HTTP) because the server supports upgrade-insecure-requests.
  3. But the browser blocks these files from using HTTP due to its security policy. This stops the icons from loading and breaks JavaScript calls.

If this is the case, it suggests the server is already set up for HTTPS so hopefully to fix this you just need to change the URL to HTTPS in $CFG->wwwroot in config.php which is in the root of the Moodle source code folder on the server. E.g.

$CFG->wwwroot   = 'http://mycollege.example.com/moodle';

becomes:

$CFG->wwwroot   = 'https://mycollege.example.com/moodle';
