Mobile Joomla Breaks HikaShop - What now?

Hi,
My Hikashop install does not accept the Authorize payment notifications with Mobile Joomla enabled.

I can deal with Mobile Joomla not allowing mobile users to checkout, but I can't turn off my shopping cart.

Is there any way to 'pass through' these requests?  What are my options?

Thanks,
Paul

Does your site work well when MJ is disabled? It's rare chance that MJ breaks any other component.

It seems that the payment request sent from authorize.net to HikaShop with the payment information in the POST is being redirected to another URL without the POST information when MobileJoomla is activated.
Thus, when it reaches the payment notification processing in HikaShop, the payment information is nowhere to be found and the order cannot be validated.

The notification URL is not SEFed and looks like that:


Would you have any idea of why this would happen ?

for clarification . . Joomla 1.5.26  Hikashop 1.5.7 MJ 1.0.3.1
