Collection pages are blank

[DetailsBoutique]

We have our collection pages set to Automatic, Product Type, and Any Condition. The products used to all show in the collections, but for some reason the collection pages are now all blank.  You can see the products in the back-end on the collection page, just not on the front end.  We're using the Mr. Parker theme.  Here's a link to the shop, we would appreciate any insight!  https://detailsboutiquehawaii.com/

Hello @DetailsBoutique ,

Seems code is missing but can't confirm without checking the code.
I suggest install a new copy of theme and then check or you have to hire someone to check it.

Thanks
