SSL & Oscommerce

Hello Guys & Gals I have just installed a SSL certificate on my website however i having issues with some of the code which is displaying the error "this page contrains both secure and nonsecure items. Do you want to display none secure items" i setup a test oscommerce site on my domain, and that is working perfectly. So i assume its got to do with some coding that is hotlinking or link images or is calling a non-secure link over Http://. Also from what ive been told all of my links go back to unsecure version of my pages. as they are all direct links to the index page. And i have activated the admin side, however there is no messages of any ssl at all. I need this to be ammened also. Looking forward for your bids You must have had expersince with SSL before.
