I faced a problem on my site at remote which is related to session, which is running properly at local.There was a echo"Hellooo"; on header.php to show the string on browser, but when i deleted it & uploaded again to show then this hello is still echoing. Also I saw that when i log in 1st time then printed a session variable on remote at the header portion.But after log out when i log in again A basic php page is giving the actual value where a query is running and fetching from database but when it is showing on page at header then it is taking the previous session variable's value.Means the 2nd user never can see his result because it will shown the previous user details. What to do in this case?
