Hi All,I've recently migrated server and upgraded to 1.10, after the upgrade I was having a problem where I needed to login to post a reply (similar to: https://github.com/osTicket/osTicket/issues/3454) I've updated to PHP 7.1 and that problem was resolved.Now my session has expired I can't login to SCP, getting a white page with Valid CSRF Token RequiredChecking logs shows:PHP Warning: session_start(): Failed to read session data: user (path: /var/lib/php/session) in /home/support/public_html/include/class.ostsession.php on line 86Folder is writeable and here is the contents of a session file:_lang|s:"en";adminlang|s:"en";LSWebUser|a:{}LEMlang|s:"en";I've also tried clearing cookies and truncating the ost_session table, no new entries are created.Each time the login form is refreshed I'm getting a different __CSRFToken__Previously on PHP 5.6 I had suhosin enabled but I had to remove prior to the PHP 7.1 update.Any suggestions for further troubleshooting would be much appreciated.Kind regardsJez
