Thank you for your reply.

I can access the Host Settings page and also tried to restart the application, but the errors still appear.

I can access the Site Settings page but get an error when trying to save the page:

Error: Site Settings is currently unavailable.

 Hi Sebastian

Thank you for the feedback.

Unfortuanately I am not making progress - in fact I am moving backwards.

I have played around with the setting on the Host Settings page and am now not even able to log on anymore - sigh...

I get the error : Login Failed, remember that Passwords are case sensitive

No matter which username and password I use - I get that error. Also, when I try to do a "Forgot Password" I get the message - The password could not be sent...
