Make sure your database host setting is 127.0.0.1 instead of localhost.

    This is a DB connection issue. I faced this while DB server was down. Before replacing 'localhost', better check your DB connection is working – augusto Oct 5 '18 at 9:05
  • Also, it is worth to check file permissions since I didn't check the symlink I had used and the original file used r-xr-xr-x (555). Changed to 755 and this error was fixed. Would be nice if a better, more specific error would be logged by Drupal. – Gugols May 20 at 22:42
