TIP FOR THEMES

When I want to either customize a theme or change themes, I save a COPY of my current theme and rename it with the date (i.e., Classic 6/11/17).

By doing this, I have a stable copy that I can fall back on.

I then change the PUBLISHED (current) copy of the theme. If I mess up, I just re-publish the COPY I made, and I'm back to normal. 

To make a copy:

1. Click Online Store
2. Themes
3. Click the ACTIONS down-arrow and choose DUPLICATE (Now you have a copy of your current, published theme. The copy appears in the list below the current theme.)
4. Click ACTIONS on the Copied theme, and choose RENAME
5. Enter a name, using the date if you want (Now you have a "preserved" copy of your theme as a back-up).

Hope that helps!
