Fatal Error after clicking confirm

[nvomedia]

Hi,
I use Virtuemart 3.0.8 on a Joomla 3.4.1 site.

When i click on 'Confirm' in the cart, this message is shown:


A fatal error has occured. Please check your log files.

No more, no less.

The errorlog in /logs/com_virtuemart.log.php doesn't have any information about this error.
PHP memorysize is 128 MB, wich is using 24 MB (joomla debug information), so that's not the problem.

I have done some searches but didn't find an error like this. So i'm wondering if you can help me?

Thanks!

No URL. But start with updating, test on a backup of the site, of course.  http://forum.virtuemart.net/index.php?topic=118683.0
