I am using a multi users application running on a Wamp server 3.1.0. (PHP Version 7.1.22)

Sometimes ,i get this error and i want to know which function or controller is causing this

ERROR - 2020-02-26 09:22:56 --> Severity: Warning --> Cannot modify header information - headers already sent by (output started at C:\wamp64\www\system\libraries\Session\Session_driver.php:49) C:\wamp64\www\system\core\Common.php 570
ERROR - 2020-02-26 09:22:56 --> Severity: Compile Error --> Declaration of SessionHandlerInterface::close() must be compatible with SessionHandlerInterface::destroy($key) C:\wamp64\www\system\libraries\Session\Session_driver.php 49

I already changed log_threshold value to 1 to get error log, but i got same result

$config['log_threshold'] = 1;

Check any controller you closed using ?> remove that form there then check your log – Boominathan Elango Feb 26 '20 at 10:09
what is the line code you are getting error? – ahmednawazbutt Feb 26 '20 at 10:15
@BoominathanElango i checked all, no ?> in controller – Fray Feb 26 '20 at 10:51
@ahmednawazbutt i only got 2 lines with no information – Fray Feb 26 '20 at 10:53
from my experience, if I have some data and I var_dump or print_r it, this warning appears. with echo I dont get any. No idea why – ahmednawazbutt Feb 27 '20 at 15:37
