note 23578 added to ref.session

Hello all, I encounter problem described below: I write the program with testing OS linux 7.2 and it 100% works well. But after migrated to the production machine with linux 6.2, sometimes it works but sometimes it doesn't, while I just do the same procedures to test (open new IE window, open the page) When it fails, only half of the page is printed out. Since the appearing half contains a form, I try to submit it but "Cannot display webpage" is shown. When I remove all the code related to Session, it 100% displays the whole web well. Can anyone help? I need to use session. -- http://www.php.net/manual/en/ref.session.php http://master.php.net/manage/user-notes.php?action=edit+23578 http://master.php.net/manage/user-notes.php?action=delete+23578 http://master.php.net/manage/user-notes.php?action=reject+23578
