Access Denied. Unable to establish a PHP session. – Knowledgebase


I was getting below error while accessing phpMyAdmin –

Access Denied

Unable to establish a PHP session.

If you believe that this is in error or inadvertent, contact your system administrator and ask them to review your server settings.

1. ‘/tmp’ directory is not present – ‘/tmp’ directory under cPanel >> File Manager >> /home/$user is not present.


2. Incorrect ownership of /home/$user/tmp folder. Set ownership as $user.

# chown $user. /home/$user/tmp


3. Incorrect Permission- Set permission of the tmp folder to 755.

#chmod 755 /home/$user/tmp
Note :- Make sure to replace $user with your account’s username.

Let me know if you’ve any thoughts
