Title: Cart Subtotal Error Last modified: October 7, 2021 --- # Cart Subtotal Error * Resolved [jeskremer](https://wordpress.org/support/users/jeskremer/) * (@jeskremer) * [4 years, 7 months ago](https://wordpress.org/support/topic/cart-subtotal-error/) * Kind of at wits end on this one. I haven’t been able to find much documentation on it either. I’ve tried a standard theme, I’ve turned off all plugins except Woo. I’m not caching and have cleared the browser, but I cannot add to the cart, remove an item in the cart, and when live shipping plugins show the options, the total on the page will not adjust when checking different prices for shipping. * Here is the error code being thrown: * 2021-09-07T00:21:36+00:00 CRITICAL Uncaught Error: Call to a member function get_cart_subtotal() on null in /chroot/home/diplomas/diplomastop.com/html/wp- content/themes/blocksy/inc/panel-builder/header/cart/view.php:152 Stack trace:# 0 /chroot/home/diplomas/diplomastop.com/html/wp-content/themes/blocksy/inc/helpers. php(800): require() #1 /chroot/home/diplomas/diplomastop.com/html/wp-content/ themes/blocksy/inc/components/builder/builder-header-renderer.php(397): blocksy_render_view()# 2 /chroot/home/diplomas/diplomastop.com/html/wp-content/themes/blocksy/inc/components/ builder/builder-header-renderer.php(680): Blocksy_Header_Builder_Render->render_single_item()# 3 /chroot/home/diplomas/diplomastop.com/html/wp-content/themes/blocksy/inc/components/ builder/builder-header-renderer.php(580): Blocksy_Header_Builder_Render->render_items_collection()# 4 /chroot/home/diplomas/diplomastop.com/html/wp-content/themes/blocksy/inc/components/ builder/builder-header-renderer.php(288): Blocksy_Header_Builder_Render->render_end_placement()# 5 /chroot/home/diplo in /chroot/home/diplomas/diplomastop.com/html/wp-content/ themes/blocksy/inc/panel-builder/header/cart/view.php on line 152 Viewing 2 replies - 1 through 2 (of 2 total) * Plugin Support [abwaita a11n](https://wordpress.org/support/users/abwaita/) * (@abwaita) * [4 years, 7 months ago](https://wordpress.org/support/topic/cart-subtotal-error/#post-14946447) * Hi [@jeskremer](https://wordpress.org/support/users/jeskremer/), * The error suggests that this has something to do with your theme – [Blocksy](https://creativethemes.com/blocksy/). * Just to check, is the same error still thrown when you’ve switched to the Twenty Twenty-One theme and you’ve disabled all plugins apart from WooCommerce? Here’s the conflict test guide for reference – [https://docs.woocommerce.com/document/how-to-test-for-conflicts/](https://docs.woocommerce.com/document/how-to-test-for-conflicts/). * * If yes, could you share with us your System Status while still in this basic configuration (only WooCommerce active + Twenty Twenty-One theme)? You can grab the System Status from **WooCommerce → Status**. * * If no, you’ll want to check with the Blocksy theme authors for assistance. Here’s their support page – [https://creativethemes.com/blocksy/support/](https://creativethemes.com/blocksy/support/). * Thanks. * [MayKato](https://wordpress.org/support/users/maykato/) * (@maykato) * [4 years, 7 months ago](https://wordpress.org/support/topic/cart-subtotal-error/#post-14970987) * Hi [@jeskremer](https://wordpress.org/support/users/jeskremer/) * We’ve not heard back from you in a while, so I’m marking this thread as resolved.
