Problem with widget

Do you mean you see this error when you open the Widgets page?

Could you also please share a copy of your site’s System Status? You can find it via WooCommerce > Status. Select “Get system report” and then “Copy for support”.? Once you’ve done that, paste it here in your response.

Yes when I open the widget page I see this error.

Hi @nickyfulls ??

Fatal error: Uncaught Error: Call to a member function get_cart() on null in /usr/www/users/xyz/wpcontent/themes/<strong>vino</strong>/framework/modules/woocommerce/widgets/woocommerce-dropdown-cart.php:113

I want to let you know that the error that you are receiving is coming from your theme Vino.

This kind of problem is usually caused by a conflict with your theme or with another plugin.
?
The best way to determine this is to:

• Temporarily switch your theme to Storefront
• Disable all plugins except for WooCommerce
• Repeat the action that is causing the problem

If you’re not seeing the same problem after completing the conflict test, then you know the problem was with the plugins and/or theme you deactivated. To figure out which plugin is causing the problem, reactivate your other plugins one by one, testing after each until you find the one causing conflict. You can find a more detailed explanation on how to do a conflict test here.

Before you start

First, please make sure you have a good backup in place of your full site and database.

Second, I would suggest installing a plugin called?Health Check & Troubleshooting. This is a plugin developed by the WordPress community and it allows you to disable plugins without affecting your current site visitors.

If the issue gets fixed when changing your theme to the Storefront, then please reach out to your theme support team as they are the best equipped to help you out.

Cheers!

Hey @dheniellguimaraes ??

Please create a new topic so that we can help you there.

This seems to be a problem with a few themes all made using a shared framework. The issue is related to the new WordPress widgets screen.

I was able to access the widgets screen again by installing the new “Classic Widgets” plugin.

I would like to know in order not to have these problems of updates among which templates you recommend for an e-commerce.

Hi, I have the same problem with the same widget, my theme is Endurer:

Error: Call to a member function get_cart() on null in /home/…/www/wp-content/themes/endurer/framework/modules/woocommerce/widgets/woocommerce-dropdown-cart/woocommerce-dropdown-cart.php:38

Did WordPress will make an update to fix this incompatibility or should we have to use the “classic widget” plugin forever ?

Hi @nickyfulls,

I would like to know in order not to have these problems of updates among which templates you recommend for an e-commerce.

We’d recommend visiting the WooCommerce Themes Showcase to find the perfect design for your store here:

@tresaury Please open a new separate thread and we’ll be happy to help you there.

Thanks!
