Today I have a really important but simple tip for you.
One that you should do right away.
Backup your theme
Your theme is what makes your store work.
It's what lets customers see and buy your products.
It shows off your brand.
It's what many apps hook into to do their thing.
It's also something that can break very easily.
So right now, not tomorrow, not later today... right now, go into Shopify and backup your theme.
It will take you 1 minute to click a few buttons and then Shopify will email you a copy of it you can save somewhere.
Hopefully you won't ever need it but if you do, you'll be happy you did this. Especially if bad things happen during a busy time.
