Re: out of stock on front, when it's in stock at back end
So far there is "light in the tunnel"..
....I think I figured out how to fix the 'out of stock' nonsense, and also FINALLY got your new products to show up in the store.
For the 'out-of-stock' I just turned off 'Manage Inventory'. You *might* have to set this manually for each item (in which case an export/import might be easier).
For the items not showing (like this one: https://gullprint.com/iron-man-3-characters.html ) , I had to rebuild the indexes manually. Now, Magento is supposed to automatically run the indexers and update the contents but it doesn't look like it's been doing that for some reason. I'm going to see if I can figure out what's up with that and fix it, but at least now you can work on selling your shirts, and people can see new items as you put them up once I get the index thing working automatically....
