Alright - I think I know what went wrong. When I ran the install script a couple of years back that modified the code on my server.
Last week I went in and modified the code on my local and then when I uploaded it, it was missing all of the code that was changed with the install.
So now I need to go in and manually modify the code to get the connections correct again.
Is there a list of the files and variables that need to be set for people that do the install manually and dont run the install script?
