This is somewhat to do with wp e-commerce and more with the theme... getting next to no help from the theme creator so I figured it's worth a shot here, since it's wp e-commerce related and someone might know what's going on with the shopping cart.
I posted earlier about how SSL was suddenly only partially encrypting at checkout. I tried the WordPress HTTPS plugin and it didn't help. I activated a different theme, and poof, the site was secure and verified again. However, my shopping cart was now broken. :( Where the price was listed was this error:
Fatal error: Call to undefined function curSimble() in /home/blahblah/public_html/wp-content/themes/oldtheme/wpsc-shopping_cart_page.php on line 64
I had temporarily switched it to twenty twelve (and every other theme except "oldtheme" gives me the same error) just to get things straightened out. How is it that the old theme has a say in the other themes? I'm bashing my head against a wall here. I have a pretty large store (3k+ items) or I'd just cut and run.
For now, I have it back on "oldtheme" and have my only payment method as PayPal currently (as opposed to offering credit card payment directly) so that my store can chug along somewhat normally for customers, but this is not ideal. Any ideas on just how I can fix this?
Thanks in advance to anyone who can clue me in.
