Need someone to fix and upgrade my website. I'm using Agoracart 5.1 Pro Version. There are a few features that used to work before and now it's not working. 1. order notification - customer can not get a copy of invoice emailed to him/her when an order is placed. 2. A link in manager.cgi to change Agoracart settings is broken. It says "403 Forbidden. You don't have permission to access /store/protected/manager.cgi on this server. Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request." 3. I may need to upgrade to version 5.5. Need some advice if it's worth doing it.
