Sessions not deleting

It's in the public_html folder. 

Does your CodeIgniter installation start at /var/cpanel/php/ ? Or, stated a different way, is the main CodeIgniter file index.php found in the /var/cpane/php/ folder?

Sorry if I was not clear, but what I'm asking for is the full path to the public_html folder.

The reason I ask is that your statement:

...session files are building up in: /var/cpanel/php/sessions/ea-php55

begs the question of whether the path /var/cpanel/php/ leads to the public_html folder - or not.  If it does not, then all those session fles belong to cpanel and not to CodeIgniter.

The full path is: /home/user/public_html
Is that what you mean? If not, how do I find the info you are looking for? 

Thanks!!
