Hi

As replied in the support ticket :

In the configuration of the extension, there is a config option called Fix complete order button issue . Just set it to Yes and It will work fine .

One note here : I see that you set your site to offline. So if you test it with Paypal, you won't see the orders show up in the back-end after you made payment because Paypal IPN could not reach an offline site to notify the system about the payment (something related to technical) .

So if you want to use it with paypal, set your site to live before testing it .

Thanks,

Tuan
