According to the documentation for remove_action() the function name and priority must match the usage where the function was hooked. You have made a common sense assumption that a higher priority should be used for the removal but I believe that is the cause of the problem.

This is known as array dereferencing and is only available in PHP 5.4+ To support older versions, you need to assign the array, and then access the index: $data = get_post_meta( $product_id, ‘_product_image_gallery’ ); $gallery_pictures_id = $data[0]; Having said that, in your case use the third argument “single”: $gallery_pictures_id = get_post_meta( $product_id, ‘_product_image_gallery’, true );
You have a structural problem with your data. Serialized data in the database is terrible if you need to search over pieces of that serialized data. There is no reliable, efficient, and certainly no easy, SQL query to search over serialized data. “serialization” is a PHP mechanism. It isn’t SQL. To the database that is … Read more
