I add the product in cart at 10:00 am then when i refresh the page at 12:00 pm i see cart is empty automatically . I check the admin settings there are we set the time [ 31536000 ] in Persistence Lifetime (seconds) which is almost 1 year . In the admin Cookie Lifetime is also [ 31536000 ] . In php.ini file [ session.gc_maxlifetime ] is also more then 2 hours . But the cart is empty after hours . I set 300 seconds then the cart empty after 5 min but if i set more then 31536000 or any other time which is more then 2 hours time then cart empty after 2 hours automatically . I check the log files to look out for any error in logs but there are no errors in log files. Could anyone suggest regarding this so i can proceed forward.
