error 500 when viewing shopping cart (SOLVED)

[stylebreak]

Hi,
I've installed virtuemart V 2.0.26a together with AIO V 2.0.26 in a joomla V 2.5.17 environment. After giving an article in the shopping cart appears a confiming pop up window (... was added...) with the possibility to show the shopping cart.
But when I want to view the shopping cart an error 500 occurs.
I' appreciate any help. thanks.

Do you have any more informations about the error, e.g. server-logfile?

The hosting reported me the following two error messages (I replaced the client-adress and the domain-name with XXX )

Get the file from here:  http://forum.virtuemart.net/index.php?topic=121130.msg413758#msg413758

Rename it as  config.php and use it to replace the existing file in  administrator/components/com_virtuemart/helpers/

Then test.
