HELP PayPal Express Won't ReDirect

Hi, I have a few problems:

1. I purchased SSL from godaddy, so my checkout is secure. They did install it, but my site doesn't seem to be using the SSL. When I go through the checkout process it still runs via http NOT https How can I fix this?

2. When I use my Paypal Express. Everything is fine except when I am being redirected to my website (it states its not secure, problem #1) Even though its not secure I still click okay. But then I receive 4 Error messages.

Warning: strstr(): Empty delimiter. in **/includes/modules/shipping/zones.php on line 230
**
Warning: reset(): Passed variable is not an array or object in **/includes/modules/order_total/ot_tax.php on line 38
**
Warning: Variable passed to each() is not an array or object in /includes/modules/order_total/ot_tax.php on line 39

Warning: Cannot modify header information - headers already sent by (output started at /includes/modules/shipping/zones.php:230) /includes/functions/functions_general.php on line 86

PLEASE HELP! Any advise would be great. I think I might need to fix the SSL problem first but I have no idea if there are related. THANKS

1. Once you've had your hosting company install your SSL certificate, and you have confirmed that going to "https://your_site.com" actually works without an error, you can turn on SSL support in Zen Cart following the procedure in this FAQ:

2. If you are using v1.3.7 and haven't installed the latest patch for PayPal, do it now:
