It is hard to explain what CSRF Tokens are, but it is an osTicket security function. And those warnings are competely normal in osTicket. Notice that you bought osTicket Awesome on July 10th, but the first warning on that page is July 9th. The CSRF tokens have nothing to do with osTicket Awesome or this issue.
I only see one DB error, so that seems okay. But please post what it has for details.
