Error: Unable to start session

I just installed PIWIK today 12/08/15.

I got to the end of the installation process and after clicking the login button I get:

Error: Unable to start session. Please check that the web server has enough permission to write to these files/directories:
For example, on a GNU/Linux server if your Apache httpd user is apache, you can try to execute:

I’ve run the script to change the permissions, which set them to 0755 (Still didn’t work, no change)
I also added: session_save_handler = dbtable
to the config.php file, which didn’t change anything. I’m still unable to login and I’m still getting session error.

I confirmed with a phpinfo() that is disabled.

Please advise.

I resolved this. It was including an additional file from my server config.
Not a problem with the software.
