Not loading

The Page not loading or slowness in loading has very little to do with Job Manger if any. This is usually an indication of your shared hosting platform or some other configuration on your site that is causing your entire site to load slow.

Looks like your DNS look time is pretty high too. You can review this yourself: https://tools.pingdom.com/fpt/ Then share this with you ISP.

You could also be experiencing a Theme and or Plugin conflict, so I would check for that too.
