Since updating WooCommerce to 10.1.0 I've been getting HTTP 500 errors and critical error messages on my product pages.

Turning off the WPC Product Quantity plugin solves the problem, as does rolling back WooCommerce to 10.0.4

Just to confirm, the update has worked.

Thanks!

Hi,

I am having the same issue using the premium version 2.4.2, but I don't see an update available.

Hi,

I just wanted to see if there's an update on this?

Thanks,

Dave

Hi Dave,

It might be best to start a new ticket with your issue.

I suspect they have marked this as solved, as they sorted my problem.

Thanks Dan, but for some reason it is blocking me from opening a new ticket.

I’ve encountered the exact same issue with the PRO version of this plugin. I don’t understand why the fix was released for the free version first, while the paid version hasn’t received the update yet.

In the meantime, I’ve temporarily resolved the issue by comparing versions 5.1.0 and 5.1.1 of the free plugin. The only change I found was in the wpc-product-quantity.php file, where lines 84–86 were commented out:

// default input 
//add_filter( 'woocommerce_quantity_input_min', [ $this, 'quantity_input_min' ], 99, 2 ); 
//add_filter( 'woocommerce_quantity_input_max', [ $this, 'quantity_input_max' ], 99, 2 ); 
//add_filter( 'woocommerce_quantity_input_step', [ $this, 'quantity_input_step' ], 99, 2 );
