JobBoardWP error

We have started using this plugin and we love it, however just recently we have been getting reports that the jobs are not displaying when people go to our jobs page.

When you click on load more jobs, nothing happens. When you refresh the page (Mobile or Web) all the jobs appear, but most people don’t do that and think there is an issue.

Any help appreciated.
