[Plugin WP Ecommerce Gold Cart]

I’m having trouble with Gold Cart. There was a bug with the latest WP Ecommerce update where orders were not storing properly. The Customers were getting charged, but their orders were giving an error when getting inserted into the database. The fix for this was modifying a line of code to cast a certain variable as a float before inserting it into the db.

That fixed the problem of not storing the orders, however now the orders are not being sent to Authorize.net properly. In the process of trying to fix the issue, we updated Gold Cart. Our license is current, and I have regenerated the Authorize.net API key since updating. What could be causing this issued?
