Blank shopping page

Hello!
I have a problem with the shopping page. Whenever I click on the categories or the subcategories the page goes totally blank. I have no idea how to solve this so I hope you can help me! Also tried to disable the plugins but to no luck..

Im using the MobileStore theme and the name of my site is https://www.lacharla.se/

Best regards
Amina
