Doensnt work with The Shop Theme

To further help with troubleshooting, you could put this line as the 1st line of the function qib_enqueue_script() in plugin’s PHP file:

echo 'test';

This would give an answer to whether the function executes at all. If the ‘test’ doesn’t show up on the top of the screen, you may try to change this line:

add_action( 'template_redirect', 'qib_enqueue_script' );

to:

add_action( 'template_redirect', 'qib_enqueue_script', 20 );

and this:

add_action( 'template_redirect', 'qib_add_to_cart_quantity_handler' );

to:

add_action( 'template_redirect', 'qib_add_to_cart_quantity_handler', 30 );

The “test” shows up, so the function executes and the other code lines that I gave are definitely not needed then.

The problem is with built-in WooCommerce function wc_enqueue_js. Somehow the script doesn’t get added to page’s HTML. It’s definitely not a simple bug because it works correctly on a few test environments. I had no other reports of such a problem and version 2.3. was released a couple of weeks ago.

Please deactivate the plugin and check whether error 500 still appears on page load. If it does, it may be the reason why the wc_enqueue_js function breaks. If there is no error 500 after deactivation it means that the plugin causes it, which would be very strange and hard to troubleshoot.

The error 500 (in chrome F12, Network tab, then reload the page) still persists with the plugin deactivated. It means that the HTML document is not correctly loaded for some reason. The 500 errors are rather hard to troubleshoot.

Probably this error also happened with the old plugin version but using a separate file for the scripts made the plugin work correctly anyway. There is a big chance that when this error is gone, the plugin will work as it should.

It means that something, possibly your theme uses WC()->cart->get_cart_url() that no longer works since WooCommerce version 2.5 and wc_get_cart_url should be used instead.
