1. Open php.ini and comment php_fileinfo.dll disabling it.
2. Restart and go to user profiles.
3. Observe error:
Fatal error: Uncaught Error: Call to undefined function mime_content_type() in C:\Development\zabbix-src\release\4.0\frontends\php\include\sounds.inc.php:27 Stack trace: #0 C:\Development\zabbix-src\release\4.0\frontends\php\include\views\administration.users.edit.php(345): getSounds() #1 C:\Development\zabbix-src\release\4.0\frontends\php\include\classes\mvc\CView.php(199): include('C:\\Development
