I am trying to update a site from 220.127.116.11 to 18.104.22.168.
I worked through the steps outlined here and it went fine except that my new site doesn't seem to recognize any my extensions. Previously in the System > Configuration menu there were menus in the left-hand bar for 'Capacity Web Solutions', 'Amasty' and 'aHeadworks' but now I just have the basic options (General, Catalogue, Customers, etc).
What have I missed? How do I get Magento to recognize the extensions?
