Fatal Error with Cart 66 Shopping Cart Widget

[magmed]

I just installed and activated WP Affiliate Platform on a site running Cart66 Lite Version 1.5.1. I got this error on my sidebar where I have the Cart66 shopping cart widget:

Fatal error: Cart66CartWidget::widget() [cart66cartwidget.widget]: The script tried to execute a method or access a property of an incomplete object. Please ensure that the class definition "Cart66Cart" 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 /home/magmed/public_html/wp-content/plugins/cart66-lite/models/Cart66CartWidget.php on line 19

If I remove the widget it is fine, but I really need to have the shopping cart shown in the sidebar.

I deactivated the WP Affiliate Platform plugin

I am using WordPress version 3.5

Any ideas how to fix this?

Reading that error, it doesn’t seem to have anything to do with the affiliate plugin. Did you try upgrading that plugin to the latest? I know that 1.5.1 is not the latest. On my test site I installed the latest copy of both the plugin and I don’t see any error.

I updated the Cart66 Lite plugin to the latest version and activating the WP Affiliate Plugin still produces the same error on the Cart66 Widget.

However, I also added both plugins to another test site and there was no problem with the widget on that site. I tried different themes, but that didn’t change anything.

In the error message it mentions line 19, which reads:

$this->_items = Cart66Session::get(‘Cart66Cart’)->getItems();

Is there anything obvious that needs changing in that line?

This sounds a little strange. That line of code you are referring to is coming from the cart66 plugin so I couldn’t advise you on that.

I would delete both the plugins from the install where you see this error then install a fresh copy of the plugins. You won’t lose any data if you re-install the plugins.

I reinstalled both plugins and the same thing happens. I also noticed that with the WP Aff Plugin activated, the WordPress admin bar that appears at the top of the front end of the site disappears, and there’s just a white space where the grey bar should be.

Maybe I can help you) During couple of days tried to deal with just the same error.

Please, open Dashboard. Go to Cart66 -> Settings -> tab Debug -> Session Management and change Database Sessions to YES.

Save changes:)
