As my admin account will be logged out for every 1 hour, I am wondering if there is any way that I can do to change my the session lifetime for all my admin accounts.
Here are what I have done:
Magento backend > Configuration > Advanced > Admin > Security > Session lifetime(seconds): 86400
Magento backend > General > Web > Session Cookie Management > Cookie Lifetime; 86400
However, it is still not working. Is there any more things I have to change in order to extend my admin session lifetime?
