I really want to set up another stream through the server
but when I click settings -> mount points, the create new button isn't even clickable
how can I make it?
all I have is my "stream" mount point right now, and im running my main stream off of that because centova wont let me make another mount point ._.

Your mount point limit is likely set to 1.  If you're the admin, increase it on the Limits tab.  If you're a client of a hosting provider using Centova Cast, contact your hosting provider about increasing your limit.
