After upgrade to Piwik 1.6 many users are reporting "Unable to start session" messages. It seems to happen when the piwik/tmp/sessions directory is not writable.
INstead we should detect this before trying to start the session and if the directory is not writable, return the standard piwik error message showing the "chmod" help command.

Maybe the whole tmp/ folder should be checked more often?

Definitely a problem across the board...

(In [5587]) Fixes #2717

  • Now displaying better error message including commands to type to fix the problem
  • Suggesting to enable db session when piwik is already installed (in case the of webhost /user changed directory permissions)
