Installing Magento Extensions : Pre-install Checklist
We spend a lot of time testing our extensions on fresh installs of Magento. However, there are a lot of different ways to setup, customize, and add-on to Magento - please follow this checklist before starting your install, to safeguard your site. You should do this before *every* extension install (not just ours!).
1) Backup your database - eg. using phpMyAdmin or the command line, make a copy of your database
2) Backup your /app folder - this is the fastest way to fully revert if you need to - easiest to put it next to your current /app folder (e.g. 'app_bkp'), that way you only need to rename the two folders to revert
3) If you have compilation enabled for your site, disable it - if you're not sure if you have this turned on, check System > Tools > Compilation
