My suport has disappeared for +appointments?

I have had big problems with a question:

https://premium.wpmudev.org/forums/topic/wrong-times-are-booked-in-the-calendar-of-appointments#post-881554

I have done what she asked me about but nothing happens. Now my calendar completely wrong and I do not know what to do to correct the problem.

Maybe she has gone for the day but it can not be like this. Please help

For a while I had a problem with writing questions. Your page said I had to become a new member . Thankfully , it was corrected . I get very nervous in my dealings with you
