title: zoom is not function in porto magento 2 demo 1 theme
body: <p>I'm frontend developer. I'm using <code>Smartwave porto magento 2 demo 1 theme</code>. Suddenly on product detail page zoom on hover function not working. I have uploaded old <code>pub - static</code> folder where zoom is working properly. But here is still error in console zoom is not function. Where to check error? even i copied whole zoom function code where <code>zoom function</code> is called. Still no luck. Please let me know. What I'm missing or where to check because I'm not magento guy. Thank you.</p>
