I installed the following system
1. WP 3.5
2. Wp e-Commerce
3. Your plugin
I use sisow as payment portal
Configured your plugin to use sisow 'ideal basic' variant
When I make a succesfull payment the page is returned as
And then nothing happens ... the order is not confirmed and no notification mail is sent.
If I look at the code of your plugin I see that it creates the form with the correct succes url (containing the field transaction_id). But apparently sisow does not respect this url anymore and sends me back with the above parameters in the url (like trxid and ec)
So I conclude that ideal_basic is no longer working or am I missing an option.
Would it help to change to ideal advanced (and to get sisow so far that the give me that extra upload box for the key file)
By the way if I paste the succes url in the navigation bar it confirms the payment with notification email.
Hope for a swift reply.
