Two column product and category on mobile view

I edited the code above to exclude the product categories.
When i add just that code the problem goes away? Maybe for really small devices you will need to increase the min height.

I increased min-height to 390px and now it's displaying properly, thanks for help.

When do you guys plan to release v1.8?

Its currently in alpha/beta for public testing. feedback has been good so hopefully only a week or two before we go live.

Great to hear. We should backup functions.php and additional CSS before updating, right? Anything else?

It shouldn't be needed as your settings and additional CSS will remain intact - but it is always best to make a backup before a major update.
