All of a sudden, (without any config change), my wordpress server is down and displaying the follow error.
Warning: mysqli_real_connect(): (HY000/2002): No such file or directory in /var/www/html/wp-includes/wp-db.php on line 1653
I’ve tried changing to localhost, 127.0.0.1, adding a port number behind it but it still dosen’t work. Apache2 and mysql has been restarted and shown to be running correctly. The database is also running fine. I can’t seem to find whats wrong.
