Somehow we can not select a colour / size / etc from the link https://airsoftzone.co.uk/recon-chest-r ... word=recon
No changes we have made on the server end nor in the opencart settings. The way it used to work was it would show the button when the page opens BUT when you select a colour / size / etc. that is sold out the add to cart button would disappear and out of stock text show up instead
recon-chest-rig-condor product is a good test as ALL colors are currently sold out but now it does not seem to reacting when we chose colors from available Options
Can guys please assist what could be the issue is?
