[Plugin: Register Plus] Fatal Errors when uploading from Localhost

Hi all,

Up until now Register Plus was an awesome plugin but there are fatal errors when I upload my wordpress folder to my web server.

Basically what happens is none of the settings are retained and it breaks my registration page. It worked fine on local host but not on line.

Are the register plus settings stored in the Database? Do I need to change URLs somewhere else?

Many Many thanks in advance

Chris
