Topic on Project:Support desk

I installed MediaWiki version 1.29.0 manually, apparently successfully, but after logging in, the bottom of the front page shows this error:

Warning: session_write_close(): Failed to write session data (user). Please verify that the current setting of session.save_path is correct (/tmp) in [path to my directory] /includes/session/SessionManager.php on line 469

Line 469 is in the function "shutdown()".

I am not a PHP programmer, so have no clue how to fix this.

Any suggestions?

Try to set $wgSessionCacheType to CACHE_DB.

I am having the same problem. set $wgSessionCacheType to CACHE_DB did'n work. 

Take a look at Topic:T7irqyk4rhfy3ohk, see if that helps.
