Collections doesnt connect

Hey!

I have a problem, my shopify store all my products stopped to be shown up, the only thing ive done is upgraded my debutify plan from trial to max rank.

My products on my pages arent shown up, the collections are available and the products are in the collections

when i connect the url of the collection to the menu bar it just shows empty pages.

so ive tried to create new collection and same thing happens.

products are on online store ticked V on Oberlo so its not the problem but when i tried to create new featured collection it shows same collection every page with diffrent urls

please help.

Store: fashionalta.com
