Shared SSL problem

[Guest]

I'm not sure what I'm doing wrong here, I've set up a shared SSL for the following website http://www.fossilcavern.co.uk

the actual SSL link is this:-https://sslrelay.com/fossilcavern.co.uk

I haven't enabled it yet because when I tried initially I could get the index page but if I tried to do a test purchase as soon as I went to the view basket page I got this:-

Secure Connection Failed

An error occurred during a connection to fossilcavern.co.uk.

SSL received a record that exceeded the maximum permissible length.

(Error code: ssl_error_rx_record_too_long)

Ok so in the general setting tab I go to Directories and Folders and do the following:-

Enable SSL: Yes

Force SSL: Not sure about this one

HTTPS Root Relative Path: what should I put here?

e.g. /store/

HTTPS Absolute URL:what should I put here?

e.g. https://secure.domain.com/store

HTTPS Root Path:

e.g. /path/to/your/secure/webstore /homepages/13/d248224450/htdocs/.cavern *

I've managed to get myself a bit confused as to what I should put into the Absolute and Root paths.

Is there anything else that needs to be changed to get the system working as well.
