These errors are returning:

PHP Code:

<?php defined('SYSTEMPATH') || exit('No direct script access allowed'); ?>

CRITICAL - 2020-04-15 14:13:43 --> ini_set(): Headers already sent. You cannot change the session module's ini settings at this time
#0 [internal function]: CodeIgniter\Debug\Exceptions->errorHandler(2, 'ini_set(): Head...', '/home/user/pr...', 101, Array)
#1 /home/user/project/vendor/codeigniter4/framework/system/Session/Handlers/FileHandler.php(101): ini_set('session.save_pa...', '/home/user/pr...') 


Error logs usually look far worse because the errors are cumulative. Clear the first error and the rest disappear.

The very first error concerns something is being written before ini_set();

Search for ini_set(), add the following script and examine what is being written and clear the problem.

Code:

ini_set();
exit; // die; // stop browser execution.

Also note if the error log is deleted it will be regenerated until all errors and warnings are cleared. Far easier to only have a few errors showing.
