Debug generates error, how to fix?

Please tell me what could be the problem? Include debug climbs error.

Warning: call_user_func_array() expects parameter 1 to be a valid callback, class 'BeRocket_AAPF' does not have a method 'init' in /var/www/сайт/data/www/сайт.ru/wp-includes/class-wp-hook.php on line 286

and
Notice: the Function of WC_Product::get_dimensions called with an argument that is deprecated since version 3.0! By default, get_dimensions has an argument set to true so that HTML is returned. This is to support the legacy version of the method. To get the HTML dimensions, instead use wc_format_dimensions() function. Pass false to this method to return an array of dimensions. This will be the new default behavior in future versions.. in /var/www/сайт/data/www/сайт.ru/wp-includes/functions.php on line 4031
