Permission denied (13)' at /var/xyz/www/wp-content/plugins/wordpress-social-logi

I recently started working with WP-CLI on the server and ran into this notice.

Backtrace from warning 'session_start(): open(/my/php/session/sess_xyz123, O_RDWR) failed: Permission denied (13)' at /var/xyz/www/wp-content/plugins/wordpress-social-login/wp-social-login.php 63:
  /var/xyz/www/wp-content/plugins/wordpress-social-login/wp-social-login.php 63 calling session_start()

  phar:///usr/local/bin/wp/php/boot-phar.php 5 calling include()
  /usr/local/bin/wp 4 calling include()

I was able to solve it by setting the permissions of the folder:

sudo chown -R apache:group /my/php/session

I’m not sure this is something you can check against, or you need to throw the error so the user notices. Either way, my WP-CLI output was a bit flooded with notices until that was solved.

Here is a snippet of steps to track down where to make the change – https://codepad.co/snippet/gSrJzdAE
