Any suggestion as to what could be causing these header error messages in opencart 3.0.2.0?

PHP Warning: Cannot modify header information - headers already sent by (output started at /home/mysite/public_html/system/framework.php:444) in /home/mysite/public_html/catalog/controller/startup/session.php on line 25

Page redirection issue. However, more information is needed.

The most generated errors being found on Opencart forum originates from contributed programming. The increased counters are caused by posted redundancies of the same solutions that were already provided prior.

F. Rules:

File system/framework.php does not have Line 444. Someone or something must have modified it, and that modification is most likely to cause this.
