Going back on mobile version in 1.5.2.0 doesn't work

[aztecmedia]

Hi,

 

I know this is an older version of PrestaShop, but the issue seems to be persistent across all installations of 1.5.2.0.

 

When viewing the website on a mobile device, if you click on to a category a list of sub categories is shown. If you then use the browser or devices back button to go back, the previous page flashes up briefly and then it goes blank.

 

I'm assuming some CSS or jQuery is changing the content displayed.

 

If from the home page you continue to view a product, the back button works fine.
