title: Magento theme displays errors and responsive display after refresh
body: <p>We have a Magento webshop (1.9.3.2) with Ultimo theme, which appears to have some strange problem in a few browsers - we've discovered it's only on Chrome and Opera so far. When you first watch the website (<a href="https://www.tuinkussengigant.nl" rel="nofollow noreferrer">https://www.tuinkussengigant.nl</a>) in Chrome, it displays correctly with no JS errors. When you refresh the page, the website changes to some weird responsive mobile view and suddenly JS errors show up too.</p>
  
  <p>We've looked at the page resource of both versions (the correct one and the weird responsive view), but both of them are exactly the same. We have no idea where to look for what's wrong. </p>
  
  <p>The only thing we could already find, was the JS noconflict thing, but that's already in one of the included .js files Magento minified, so that's not the case either. </p>
  
  <p>Can somebody please push us into the right direction of where to look on how to solve this problem? Has it something to do with the async of the js file, since it's only after a refresh and not when the page is first loaded with CTRL+F5 for example?</p>
  
  <p>Thanks in advance.</p>
