Hi Jason, sorry I've been so long getting back to this.
I solved this by un-installing ALL my extensions including the deprecated server behaviours.
Then Deleted (renamed) the Configuration folder.
Then installed the deprecated server behaviours and then installed MySQLi Server Behaviours. With this it all worked as it is supposed to.
I have still to re-install all my other extensions but hopefully all will go well. If I have any further problems I will get back to this thread.
