I administer a website for a small local charity which has Civicrm 4.7.6 / Joomla 3.6.4 with php 5.6. I am wanting to upgrade all 3 to latest versions. In order to do this i need to create a test copy of my live site. When i do this using akeeba backup, civicrm is trying to access my production site. have seen civicrm documentation on this but it is undated and looks really old (references only Joomla 1.6 & 1.7). Is there a simple up to date step guide to get a working copy of my production site?
