page 404

Hi,

when I go on https://www.malheur.com/collection/ and click on BUY (any product) I get that the page can not be found ( https://www.malheur.com/collection/ajax-open?add-to-cart=variation&product_id=296 )

All I know is that noone changed nothing, and that all was functioning very well `till today.

Any help?

Thanks
