Hi,
I want to set up my site as a management site for my students. Within that there should be the possibility to communicate, upload files, calendar, etc.
I understand that there are plenty of plugins out there. Do any of you have any recommendations of good plugins that would do the job? I have found several but most of them are paid (Like this).
And my second thing is: I installed BuddyPress from within my “Pro” Dashboard. After that my site has several “activity” sites that are present in the menu, too. I could not access my admin are until i have deactivated the plugin via my FTP. Is there a bug? If yes: Here is a notice of that bug
