[solved]Error 500 on edit or add new shipment from shopping cart summary

[bobchain]

Hello,
I have a problem with error 500, when from the cart click on edit or add / change shipping or billing address.

I am using a component / plugin to view the product detail: "flexible cleanmart".

Carrying out the same operation from the user reserved area, the modification / new insertion page opens correctly by adding the verification code in the URL
/e-shop/utente/addST?new=1&virtuemart_user_id[0]=446&e....2228b=1
while if  I try same from the shopping cart summary builds the url differently:
/E-shop/user/Change-Address-Shipping?Virtuemart_user_id[0] = 0

Do you think that the problem is the plugin? the support of the component is not able.

current version joomla 3.9.15
VirtueMart 3.6.10 10211.
Database    5.6.45-log
Versione PHP    7.2.20

Thanks for your suggestion.
Regards,
Roberto

Have you tried with Protostar instead of the Cleanmart template?

Hello jenkinhill,
1) yes, i have just now tryied it and with that template work correcly.
2) by disabling the plug-in that drives the template for virtuemart, other than the graphic template of joomla (not specific for virtuemart), I managed to trace the error
Fatal error: class 'VmModel' not found in .../mysite-test.it/htdocs/administrator/components/com_virtuemart/models/product.php on line 23

Other to test or check?

Thank you very much!

I carried out a test by disabling the plugin by ftp side (renamed the COM_VIRTUEMART folder) and so also the joomla template in use, load the VM std core, and it is executed correctly.
therefore there is one or more errors in the default.php or default_address.php file of the CART folder

Compare same files on notepad++?

lack of a model class etc is often to do with the vm config not being loaded correctly ..  yes .. you will have to start with a file compare  - look for the requires and they syntax of the config load in the flex files

e.g.

if (!class_exists( 'VmConfig' )) require(JPATH_ROOT .'/administrator/components/com_virtuemart/helpers/config.php');
VmConfig::loadConfig();

Thanks for your suggestion.
problem solved with a little edit of template and upgrade of the new version of the plugin
