"Valid CSRF Token Required" in Osticket After login?

Question

My osTicket Version 1.10 is installed in PLESK Windows Server. I have tried to install XAMPP on the PLESK Windows Server but not able to start XAMPP .

Soon I get error after login to osTicket "Valid CSRF Token Required in Osticket After login" which was earlier working fine

After login I get this error:

Answer 1

in include/class.ostsession.php

Just add this line:

$this->data->session_data = "";

After:

catch (DoesNotExist $e) {
        $this->data = new SessionData(['session_id' => $id]);

So it will be:

catch (DoesNotExist $e) {
        $this->data = new SessionData(['session_id' => $id]);
        $this->data->session_data = "";

Then try to login from scratch, don't just refresh the submission.
