It is vital to test and backup before making changes

When making changes to any project, document, or even a web site, it is vital to check your changes before taking them live.

It may seem tempting to simply press the big “GO” button and hope for the best, but all too often a small change in a template or theme can have big consequences elsewhere!

As with everything, always make a backup copy of what you are working on in case you quickly need to roll-back to the last known working version with minimal downtime in the case of a catastrophic error.
