Blank shopping cart after upgrade to 3.0.18

[MySigma]

Hello!

I'm currently working on an onlineshop for a customer. She is currently using VirtueMart 3.0.17.2 and everthing is working fine. The current installed Joomla Version is 3.6.4! I'm getting two errors as soon as I'm updating VM to 3.0.18. The first one was already solved (COM_VIRTUEMART_FILE_NOT_FOUND). The second problem is a blank shopping cart. I'm mean, hitting the "show cart" button brings up an empty white page.

I think the there is something wrong with "templates/MYTEMPLATE/html/com_virtuemart/cart/default.php", but I'm not sure!? Any advice?

Best regards,
Manfred

find the 500 server error

or try the standard cart template file to see what the difference is

There is absolut nothing within the log files... no error is displayed... absolut nothing

I'm not so familiar with Virtuemart because I'm normally using ZenCart as Shopsystem, so I'm not sure what you mean with "...or try the standard cart template file to see what the difference is...". Where can I switch to the standard cart template?

Best regards,
Manfred

You can rename the cart override directory at templates/MYTEMPLATE/html/com_virtuemart/cart/  eg to cart_ and this will force VM to use the default cart templates.

Or if a one page checkout plugin is installed then you could disable it.

Enable PHP error reporting..

Renamed the directory and still have a white blank page. Maybe the bug is within the default cart template??

Enable PHP error reporting..

Is already enabled but the log file is empty and NO error is reported

When VM is installed, you must enable PHP Developer mode in VM config to show errors.

Ok. Now I'm getting an error message instead of a blank page.

Fatal error: Access level to VirtueMartViewCart::$useSSL must be public (as in class VmView) in /big/dom/xDOMAIN/www/extern/CUSTOMERTEST/plugins/system/vponepagecheckout/cart/cartview.html.php on line 20

* INFO:  "enable ssl for sensitive areas (recommended)" is NOT active.

I'm having a SSL certificate installed, but I don't use it for this testinstallation.

PHP CGI Version: 5.6.18
PHP CLI Version: 5.6.18
SSL PHP Version: 5.6.18
PHP Module Version: 5.6.18

If SSL is not yet installed then ensure "Enable SSL for sensitive areas (recommended)" is not selected in VM configuration/shop

The version of VP One Page Checkout you're using is outdated and incompatible with VM 3.0.18. Update it.

If you can't update it for some reason, in /plugins/system/vponepagecheckout/cart/cartview.html.php change

Code Select Expand

protected $useSSL; to

Code Select Expand

public $useSSL; and hope nothing breaks.

If SSL is not yet installed then ensure "Enable SSL for sensitive areas (recommended)" is not selected in VM configuration/shop

SSL is installed but not used for this testinstallation. "Enable SSL for sensitive areas (recommended)" is NOT active

@ Ghost:
Very good!! Thank you so much! It looks like it's working now. I going to do some test and give you a feedback!
