Appointment+ does not quite work

Message: Hi there,

I have just purchased the plugin.

1)When I do a test with appointment, even it shows that a time slot is

now taken, it shows no appointments in the backend and I never receive

any email about my appointment.

2) when I do a connection test for the Google Calendar, I get a blank

page – nothing to say if my connection is a success or not.

Please help me fix these issues.
