function ‘pcbpys_activate_license’ not found

  • Hello,

    I have this error in WP dashboard:

    Warning: call_user_func_array() expects parameter 1 to be a valid callback, function ‘pcbpys_activate_license’ not found or invalid function name in /home/adriend6/public_html/wp-includes/class-wp-hook.php on line 286

    It originated after installing Elementor page builder. Any advice about how to fix this?

  • I’m also getting this on a custom build website too that uses WooCommerce. Just updated via the usual way.

    Warning: call_user_func_array() expects parameter 1 to be a valid callback, function ‘pcbpys_activate_license’ not found or invalid function name in home/wp-includes/class-wp-hook.php on line 286

    Any update will be great!

    Same here. After install Polylang plugin.
