Since a few weeks I'm using two themes for the Magento webshop. One for smartphones and one for desktop/tablets. The smartphone theme should only be used on smartphones, but the homepage of the this theme is also displayed on tablets. When tablet shows the desktop homepage, smartphones show the desktop homepage to. Thereby, the desktop/tablet theme shows up randomly on smartphones, on just one page (different one each time). Nothing I'm trying to solve the problem seems te work. What I've already tried:
- Clearing the cache.
- Flushing the cache.
- Disable Amasty Full Page Cache.
- Using different types of string to define the screensize.
- Adding an acception for tablet (before and after acception for smartphone).
Because it happens randomly, it's hard to investigate what's going on. The log doesn't give any information on this problem. On our development area the two different themes work perfectly. The problem apeared when I added the smartphone theme (via System -> Configuration -> Design -> Themes). I'm using Magento 18.104.22.168. Any ideas wat causes the problem and how to solve it?
