How to Grid my products

Hello and thank you for taking the itme to help me with my problem.

I’m not good with all this techy stuff and have searched for an answer, tried everything I can, but am still struggling to get my products to display in grid format.

I recently changed my products page to display in grid format, however after losing my website and restoring it I am now unable to change it back. I have edited the grid layout pluging, but nothing is happening?

My website is https://charscharms.com/store/products/

Any help would be greatly appreciated:)
