stedata (Steve Ste) on "Portfolio grid (Avada theme) is not showing on Chrome, firefox and mobile"

Hi
we have gone through a few forums and troubleshoot and we can't see to find out why this is happening.

The portfolio grid isn't showing on Chrome or firefox. It shows up fine on Microsoft Edge.
It was all working fine a couple weeks ago.
Can someone shed some light?
Many thanks in advance.

You have a javascript error:

jquery.js?ver=1.12.4:2 Uncaught Error: Syntax error, unrecognized expression: [href=#]

Usually this means you have a plugin or theme that's out of date. Check for updates for your theme and plugins.
