Getting errorException

[Bidhya (Bidhya Shrestha)]

I am getting
Whoops\Exception\ErrorException Call to undefined method Error::singleton() File:/var/www/html/admin/modules/dashboard/classes/phpsysinfo/includes/output/class.Output.inc.php:40
error every time I login the freepbx.
Also when i try to play the call recording through cdr reports recording I get following error:
Whoops\Exception\ErrorException Undefined offset: 3 File:/var/www/html/admin/modules/cdr/Cdr.class.php:460
