Hello. There are some hidden and private groups on my site, we filled them with information, and when this work has done, we decided to open this groups for users. But when we switch the privacy option from hidden or private group to public, the activity which was in the groups’s home page it is not displayed. Home page becomes clean. And when we switch the options to a hidden or private again, the activity in the home page is appear. Sorry for my English.
