    Hi there,

    On my Woocommerce shop page, there is a warning at top that reads as such:

    “Warning: call_user_func_array() expects parameter 1 to be a valid callback, no array or string given in /home/xxxxx/public_html/wp-includes/plugin.php on line 213”

    I have no clue what this means, But here is line 213 in my plugin.php file:

    $value = call_user_func_array($the_[‘function’], array_slice($args, 1, (int) $the_[‘accepted_args’]));

    And here is the webpage that it is happening on:

    Does anyone know how to fix this?

    Thanks.

  • So you are using a child but do you have this when you activate just the parent? This will let you know if the issue lies in the child theme then we can investigate further.

    Hi, and thanks for your message.

    Good call- it only happens on my child theme, not on the parent. I have done some customization on the woocommerce pages (in child theme), such as changing background color and removing things here and there…

    If you customized the shop page in your child theme, I would look there first if you don’t get the issue anywhere else.

    OK great, thank you. I guess from here I should just take out some custom code a bit at a time and see what was causing it.

    I’ll give it a try tomorrow and report back how it went. This was definitely helpful.

    Hi,

    I was able to find the faulty code in functions.php in my child theme (as you pointed out). I was trying to remove the word ‘Shop’ from the top of the page. Here is the faulty code:

    //remove ‘shop’ from shop page from WooCommerce
    add_filter(‘woocommerce_show_page_title’,false);

    I’m not sure why this code caused a problem, but I’m very glad the warning is gone. I’ll look around for another way to remove the word Shop.

    Thanks very much for your help!

    I have the exact same issue. The code add_filter('woocommerce_show_page_title',false); which I’ve also included in my functions.php in the child theme is causing the same warning message!

    Did you find an alternative way to stop the page titles showing on WooCommerce pages?

    I’ve managed to find some alternative code that removes the page titles in WooCommerce, but doesn’t result in any warning messages. So here it is for the benefit of anyone else with the same issue –

    add_filter( 'woocommerce_page_title', 'woo_shop_page_title');

function woo_shop_page_title( $page_title ) {

	if( 'Shop' == $page_title) {
		return "";
	}
}
