Critical Error on Checkout Page After WooCommerce Update

let me know which code?

Thanks for your message.

I reviewed the code in my Child Theme and didn’t find anything that should affect the Thank You page. The only customization I’ve added is two extra links in the My Account section (Special Offers and Updates). I’ve used the exact same code on another website without any issues.

Here is the full code from my functions.php:

<?php
/**
* Enqueue script and styles for child theme
*/
function woodmart_child_enqueue_styles() {
wp_enqueue_style( ‘child-style’, get_stylesheet_directory_uri() . ‘/style.css’, array( ‘woodmart-style’ ), woodmart_get_theme_info( ‘Version’ ) );
}
add_action( ‘wp_enqueue_scripts’, ‘woodmart_child_enqueue_styles’, 10010 );

/**
* Add custom Special Offers and Updates tabs to My Account
*/
add_filter( ‘woocommerce_account_menu_items’, ‘add_custom_tabs_to_my_account’, 99 );
function add_custom_tabs_to_my_account( $items ) {
$items[‘special-offers’] = ‘Special Offers’;
$items[‘updates’] = ‘Updates’;
return $items;
}

// Register endpoints
add_action( ‘init’, ‘add_custom_endpoints’ );
function add_custom_endpoints() {
add_rewrite_endpoint( ‘special-offers’, EP_ROOT | EP_PAGES );
add_rewrite_endpoint( ‘updates’, EP_ROOT | EP_PAGES );
}

// Special Offers tab content
add_action( ‘woocommerce_account_special-offers_endpoint’, ‘special_offers_content’ );
function special_offers_content() {
echo ‘<h3>Special Offers</h3>’;
echo ‘<p>Check out some of our current promotions!</p>’;

// Display WooCommerce Sale Products using Shortcode
echo do_shortcode(‘[sale_products limit="9" columns="3" orderby="rand" order="DESC"]‘);

// See More Offers button
echo ‘<p style=”margin-top:20px;”>See More Offers</p>’;
}

// Updates tab content
add_action( ‘woocommerce_account_updates_endpoint’, ‘updates_content’ );
function updates_content() {
echo ‘<h3>Website & Product Updates</h3>’;
echo ‘<p>Stay informed with the latest updates, product news, and service announcements.</p>’;
echo ‘<p>Click here to view our Updates.</p>’;
}

To test further, I even switched to the Parent Theme and tried placing a test order — but I’m still seeing the same issue on the Thank You page. That makes it even more strange, since it doesn’t seem to be caused by the theme at all.

I just switched to the Woodmart theme and the Woodmart Child theme — the same issue still persists. I’m not using any other themes.

Can you please show me which WooCommerce templates or functions are being overwritten by Woodmart? I suspect this could be causing the issue. On another website where I’m using an older version of WooCommerce, everything works fine — so this is really strange.

Thanks for the quick reply.
I also noticed a fatal error — please check the attached file for more details.

Thanks

I also checked my website and tried purchasing a product, but I saw that the problem is still not resolved.
