Top of the morning to you!

I ran into the following problem. When I try to install the MediaWiki version 1.29.2 and click set up the wiki link, I get the following error message:

PHP Fatal error: Uncaught Error: Call to a member function getIP() on null in C:\Websites\mediawiki\includes\user\User.php:2233 Stack trace: #0 C:\Websites\mediawiki\includes\session\SessionBackend.php(712): User->getName() #1 C:\Websites\mediawiki\includes\session\SessionBackend.php(596): MediaWiki\Session\SessionBackend->save() #2 [internal function]: MediaWiki\Session\SessionBackend->MediaWiki\Session\{closure}() #3 C:\Websites\mediawiki\vendor\wikimedia\scoped-callback\src\ScopedCallback.php(76): call_user_func_array(Object(Closure), Array) #4 C:\Websites\mediawiki\vendor\wikimedia\scoped-callback\src\ScopedCallback.php(56): Wikimedia\ScopedCallback->__destruct() #5 C:\Websites\mediawiki\includes\session\SessionManager.php(885): Wikimedia\ScopedCallback::consume(NULL) #6 C:\Websites\mediawiki\includes\session\SessionManager.php(195): MediaWiki\Session\SessionManager->getSessionFromInfo(Object(MediaWiki\Session\SessionInfo), Object(WebRequest)) #7 C:\Websites\mediawiki\includes\WebRequest.php(735): MediaWiki\Session\Sessio in C:\Websites\mediawiki\includes\user\User.php on line 2233 PHP Fatal error: Uncaught Error: Call to a member function getIP() on null in C:\Websites\mediawiki\includes\user\User.php:2233 Stack trace: #0 C:\Websites\mediawiki\includes\session\SessionBackend.php(712): User->getName() #1 C:\Websites\mediawiki\includes\session\SessionBackend.php(197): MediaWiki\Session\SessionBackend->save(true) #2 C:\Websites\mediawiki\includes\session\SessionManager.php(473): MediaWiki\Session\SessionBackend->shutdown() #3 [internal function]: MediaWiki\Session\SessionManager->shutdown() #4 {main} thrown in C:\Websites\mediawiki\includes\user\User.php on line 2233

I am new to the wiki and unfortunately not a PHP specialist.

The machine is of following means: Windows Server 2012. PHP 7.1.10. IIS 8.5.9600.16384. MySQL 5.7.20.

Please kindly help or point in the right direction of what is breaking and where to dig.

Could be Topic:Tmt7736t4cc5yy7o ? Any further information in your web server's error log?

Hello!

Thank you for the answer.

I was able to resolve this my identifying the variable sys_temp_dir in the php.ini

I have set it to the following: sys_temp_dir = "C:\Windows\Temp\mwtmp-IUSR" where mwtmp-IUSR is a temp folder created by the php script of MediaWiki.
