We have project, created by college of mine January.
Both me and he are members.
But in somehow with updates are applied default rights of projects (rw to subscribers) and now we don't have subscribers, no one can edit Project properties, no one can join it, nothing

You Shall Not Pass: #project
You do not have permission to edit this object.
Users with the "Can Edit" capability:
Subscribers can take this action.

How to take over permissions of project, I'm the admin of install ?
