Barclay ePDQ Essential & Extra -order not found

Hello

I could really do with some help i have installed the above and everthing work fine until the user is redirected back to the site, it then comes up with a message, order not found.

when i look at the orders in the backend they are there but have been changed to Cancelled status???

any help really appreciated

I too am having this exact same problem with orders showing as missing. Problem occurs with Paypal, Google Checkout, NoChex.

I am hosted with fasthosts and they too confirm no IP or Port blocking.

I use Opencart for 2 websites and both have the same issue.

I also have another 2 OC websites hosted with 123-reg and these work fine.

Is there a work-around to get the orders come through as pending/processing?

Also, as the orders are coming in as missing, the stock is not deducting correctly. Any one else have this stock deducting problem?

Anyone got any other ideas/suggestions?
