Test modifications

Hi,
   It depends what modifications you wish to carry out.
If you wish to try a different header/footer then I would create a different customer group with a test user within it and then add code to display a different header and footer to that customer group :

To display the site to ve taken a look at the code and I believe the easiest method would be to modify :
pcStartSession.asp and viewCart.asp. Look for :

'******************************* ' Check if store is ON or OFF '******************************* If scStoreOff="1" then     response.redirect "msg.asp?message=83" End If

Create a test "customer" and then modify the code along the lines of :

'******************************* ' Check if store is ON or OFF '******************************* If scStoreOff="1" and session("idcustomer")<>"99" Then     response.redirect "msg.asp?message=83" End If

Where "99" is set to match your test customer ID.
To make use of this either login BEFORE switching off the store, or  login to the admin pages and then place an order as your test user account/

Of course, back up the files before you change them etc.

Please note I have not tested this in any way.
