Just Installed latest version, but when trying to send a message from the built in contact.php template i get this error:

"Authorization Code Mismatch, Are you accessing this function correctly? Please go back and try again"

Can anyone help please?

Is that a fresh install or an upgrade to the latest version ?

There's a topic that may help :
