 * I moved a WordPress site that was on a sub-domain in a sub-folder to it’s own
   shared hosting account. It still uses the sub-domain but is now installed in 
   the root. Everything with the site is working fine except I get the following
   errors at the top of the BackWPup pages in the admin.
 *     ```
       Warning: session_start() [function.session-start]: open(/tmp/sess_d2513357e342f9ff4e6c3e0c07868e3f, O_RDWR) failed: session_start() (13) in /home/xxxxxxx/public_html/wp-content/plugins/backwpup/inc/class-admin.php on line 253
   
       Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/xxxxxxx/public_html/wp-content/plugins/backwpup/inc/class-admin.php:253) in /home/crmzerog/public_html/wp-content/plugins/backwpup/inc/class-admin.php on line 253
       ```
   
 * and these ones at the bottom of the page.
 *     ```
       Warning: Unknown: open(/tmp/sess_d2513357e342f9ff4e6c3e0c07868e3f, O_RDWR) failed: Permission denied (13) in Unknown on line 0
   
       Warning: Unknown: Failed to write session data (files). Please verify that the current setting of session.save_path is correct (/tmp) in Unknown on line 0
       ```
   
 * The /tmp folder has permission 0755. Does anyone have any ideas as to why this
   may be happening?
 * Many Thanks!

 * The error has gone and I have no idea why?!?! Last night I deleted everything
   and uploaded all the files using filezilla instead of uploading the BackWPup 
   zip file and extracting the files via cPanel File Manager. The error was still
   happening so I went to bed in frustration.
 * This morning the errors are gone! Maybe the server needed to sleep on it as well.
   I wish I had more information to help if anyone else has this problem. Seems 
   like the best thing to do is go to bed and let the server work it out on its 
   own.
