Ошибка: Warning: file_exists(): open_basedir restriction in effect

После установки WP-RECALL когда заходишь в раздел Add-on менеджер выдаёт вот такие ошибки:

Warning: file_exists(): open_basedir restriction in effect. File(/home/atskymas/domains/freelansa.net/public_html/wp-content/wp-recall/add-on/index.html/index.php) is not within the allowed path(s): (/home/atskymas/:/tmp:/usr/share/pear) in /home/atskymas/domains/freelansa.net/public_html/wp-content/plugins/wp-recall/functions/rcl_addons.php on line 132
