I am trying to add a visual force page to my salesforce community page, and it worked fine in sandbox. i was able to drag the visual force component onto my community in the builder. but now in my dev environment that component does not exist. any ideas?  Does NOT give me the Visualforce Page option from within Community Builder.  Guessing this is a permissions issue of some sort.  My profile is system admin within each of the sandboxes.

Suggestions please :)
