I am trying to build a mediawiki and I have installed IIS and PHP manually to do that. I did all configuration and after that I wanted to begin with the Installation of mediawiki, but then the following error occur:
So I checked my php.ini and set the Session.save_path to C:\inetpub\temp\phpsessions. There the data gets saved (see Screenshot), but the error still occurs.
Does anybody know this error and can help me, or has an idea to fix this error?
MediaWiki uses it's own session storage (in DB or memcached/redis...), but on the installer it has to use the normal php session handler... In a load balanced setup, for this scenario, you must ensure each client is assigned to the same server, otherwise a session starting on server A, if the load balancer switches to server B, this session is not recognised and you'll end with a session data lost error.
