after restarting my server i'm getting this message when trying to connect to my site. It was trying to update to latest version and than i couldn't login anymore..
Fatal error [400]: SQLSTATE[HY000] [2002] Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

Ouch, these are tricky. Did it worked before v3.9.5? Which version you had before this?
Usually these errors are just ip/port/socket issues that happens in bad configured servers and sometimes it just fails after you update something at your server.
