This is due to JavaScript/jQuery errors on your site. If another plugin, theme, or custom code has a JavaScript error, this will prevent WP Job Manager’s jQuery from running as all JavaScript is stopped whenever there is an error. Luckily enough this is something that is very easy to determine if there is an error, and what file is causing it.
You can view this by going to your listing page, clicking the F12 key on your keyboard (this will open developer tools). You will then need to click on the Console tab, go ahead and refresh the page (keeping the Developer Tools window open), and you should see some type of errors showing (normally in red).
Towards the right side of the Developer Tools window it should tell you the script file that has the error, hover your mouse over this to view the path to the script. If the script is actually output in the page’s HTML, it will say something like (index) or the name of the page. You can normally click on this to go to the code that has the issue.
Specifically this:
sfsi_plus_stick_widget
Is being called in your JavaScript but that function doesn’t exist, hence the JavaScript error, hence no jobs loading, fix that and you fix your problem.
