Click on my site, then click the next page button, to see one of the next products. I cannot figure out why it isn't working.

Any advice is appreciated.

Vm, joomla version etc ?

Joomla Ver. 3.6.5

VM Ver. 3.4.2

You have an old insecure and outdated Joomla version.
Still no info if this is a new install, not likely, updated VM, an updated PHP with outdated extensions for example. Test with protostar template.
Things don´t change by itself, what have you done ?
