Error when changing shipment method or payment method

[davidC]

Hello,

I got this message on a Joomla 2.5.11 with a VM 2.0.22c, when I change shipment method or payment method on the cart in the shop :

Fatal error: main(): The script tried to execute a method or access a property of an incomplete object. Please ensure that the class definition "VmImage" of the object you are trying to operate on was loaded _before_ unserialize() gets called or provide a __autoload() function to load the class definition in .../components/com_virtuemart/views/cart/tmpl/default_pricelist.php on line 144

Someone to help me?
Thanks

I activate the VM debugging and I see a weird thing in the object $this->cart->products :

          [image] => __PHP_Incomplete_Class Object
                (
                    [__PHP_Incomplete_Class_Name] => VmImage

"when I change shipment mode or payment mode on the front office :"

I am sorry, what do you mean with mode? and what do you mean with front office. Do you mean the checkout?

Hello,

I'm sorry for my english.
I'm talking about the payment and shipment methods.
And the problem appears when I am on the cart of my shop.
I click on Choose the shipment method and when I validate my choice.
I obtain the error. I made a screen capture.

Thanks

What is your max_memory and which payment plugins do you use?

I'll getting a similar error see below
It happens when on the cart you are trying to select the payments.  I have two payment setup.  Paypal and VM standard.

After the error occurs you can refresh the site go back to the cart and the selected payment method is now selected.

I have these two setting in the .htaccess to increase the memory and confirmed that it has taken effect via the joomla -> system information > php settings.
php_value max_execution_time 512
php_value memory_limit 256M

One other bit of information is that this has just started happening and no software changes were happening to the site.

Fatal error: main() [<a href='function.main'>function.main</a>]: The script tried to execute a method or access a property of an incomplete object.
