I went to Access Control under Apps, and clicked on new profile. I then went to edit/view calendars. On the New calendar window, I named it and listed the sites.
it turns out I can set up calendars if I first enter the time ranges in the text mode, click the green ok button, and then it goes to graphics, and if I click ok again, I can save changes and I see the applying changes message, and the success, changes applied message. However, I can’t save changes directly from the graphic mode on the calendar, because if I click on the green ok button, nothing happens. This means I have to go through an extra step to set up & use calendars.
