Steps to reproduce:
- Upgraded server and agent from 2.4 to 3.4, everything seemed to work fine.
- Login
- Displays error at bottom off dashboard and top or bottom of all other pages I tried.
session_start(): Setting option 'use_cookies' failed [zabbix.php:21 → require_once() → ZBase->run() → ZBase->processRequest() → CView->getOutput() → include() → local_showMessage() → CSession::keyExists() → CSession::open() → session_start() in include/classes/core/CSession.php:145] session_start(): Setting option 'use_cookies' failed [zabbix.php:21 → require_once() → ZBase->run() → ZBase->processRequest() → CView->getOutput() → include() → local_showMessage() → CSession::keyExists() → CSession::open() → session_start() in include/classes/core/CSession.php:145]
- So I tried the latest version... Upgraded server and agent from 3.4 to 4.4, everything seemed to work fine.
- Login
- Still displays error at bottom off dashboard and top or bottom of all other pages I tried.
Result:
Expected:
No session_start() errors.
I was able to disable this error message by modifying /usr/share/zabbix/include/classes/core/CSession.php and commenting out line 148, ($options = ['use_cookies' => 0]). I don't understand the use of a static variable in a private static function 
.
