Problem
Product variations are not displayed under the title field in BEAR bulk editor when Oxygen Builder theme is installed.
Cause
Oxygen Builder (version 6 Beta4 and higher) includes code in mods/cart.php (line 62) that disables variation attributes display in the admin area:
add_filter('woocommerce_product_variation_title_include_attributes', '__return_false');
Solution
Add this code to your theme's functions.php file to re-enable variation attributes in the admin area:
// Fix: Enable product variation attributes in BEAR when using Oxygen Builder
add_action('init', function () {
if (is_admin()) {
remove_filter('woocommerce_product_variation_title_include_attributes', '__return_false', 10);
}
}, 999);
This code removes Oxygen Builder's filter and restores the default WooCommerce behavior, allowing BEAR to display variation attributes correctly.
