AbleCommerce Shopping Cart Software

Using AC 7.0.3, ASP.NET 2.0, SQL Server 2005

I can go all the way thru to putting in a credit card, but when I click on 'Pay with card', I get a message that there's something wrong with the order. Non-specific.

The shipping is right. In the DB, all items are in the Basket tables instead of the order tables, so it hasn't been copied yet.

Where can I find out what this error is?

Please check application error log under Merchant -> Help -> Error Log, is there any error entry entered just after reproduction of checkout problem.
