Help to login to my WHMCS installation

[Pas]

Hello,

I transferred my WHMCS installation from a server to another but I have problems to login in frontend and backend. When I write (the correct) username/e-mail and password, I am coming back to login form (as if I reload the page).

Can you help me to fix this problem?

Thanks

Now I am (also) getting this error:
