I just migrate my site to localhost and everything working fine. but when i try to logged into my admin pannel then its through me error like Your current session has been expired.
I removed all the cache from the folder also change the setting from database about session expiration time.
also we have tried each and every possible solution from this thread.
Thanks in advance.
This is the perfect solution
first step: find "admin/security/session_lifetime" in table core_config_data. if not exist create one and set value to 86400
second step: clean cache (remove var/cache)
login and fix
