zabbix jQuery working on localhost but not remotely

zabbix jQuery working on localhost but not remotely

Hi,

I am using zabbix3.0.20 with apache server. When I access the webpage from localhost it loads fine but when I access the webpage remotely from another machine over the internet the page loads very slowly and incompletely. I get the following errors 

Uncaught ReferenceError: jQuery is not defined errors.

How can I troubleshoot and fix this? Thanks
