Hi,

I've been away for a few months and discovered my shop and gallery is missing! Also I'm not sure how to quick stock... Am I glitching?

The site has gone over to a new shop and gallery system. You can find the guide here - https://subeta.net/forums.php/read/854270/New-Shop-Guides

Your old shop and gallery are still there. Go to the Commerce drop down menu and they should be listed as My Shops.
