hi, i saw a few closed threds on the topics, but none that were still open for discussoin so I'm opening a new one here.

For some weird reason, I can't hide the out of stock variants in my product page although I am certain that it was working fine about a month ago!

Can anyone take a look please at my site and enlighten me? I can't seem to figure this out.



Thanks so much.
