switches from HTTPS to HTTP when Buy Now Image clicked

[vicspain]

Hello,

 

I just installed my SSL but when I goto my shopping cart via the HTTPS link everything looks OK and the LOCK is displayed. However when I click a BUY NOW image it switches out of HTTPS to HTTP.

 

I have turned on SSL in the catalog\includes\configure.php so is there something else that has to be done to keep it in HTTPS mode?

 

Thank You,

 

Vic
