PHP Notice: session_start() [<a href=’function.session-start’>function.session-start</a>]: failed: Permission denied (13) in /system/library/session.php on line 11
Opencart Session.php Permission Denied error
Have you been lately finding such errors on your opencart?
Its a improper hosting parameter issue, Its because your opencart can not write sessions to your folder called /tmp

You may find multiple solutions online for this , Like make /tmp 0777 , or add session_save_path to your session.php or many more
But I have better solution for this follow this
Step1:
Create Folder to your opencart directory say
/public_html/shop/tmp
Step 2:
Goto
/public_html/shop/system/library/session.php
Find
session_start();
Replace it with
session_save_path($_SERVER[‘DOCUMENT_ROOT’].”/tmp”);//By user
session_start();
Bingo thats it , It will start writting sessions to your
/public_html/shop/tmp directory
