[Plugin: WPtouch] Mobile site being shown when on desktop

I have seen multiple people’s posts about this issue, and the solution for them was to enter “WPtouch’s mobile user agent list into the “rejected user agents area” of the cache plugin”.

My issue is that, as far as I’m aware, I’m not running a cache plugin, but I could be wrong – the only plugins I’m running are WooCommerce and WPtouch.

EDIT: no real need to give you the site as it only shows for admins…
