Got the same problem. I think its a really tricky bug. If i post a job the vars n database are is_temp 1 and is_active 0 but it must be the other way to work. So i thought about an admin function to activate the jobs which are postetd, but i cant see the job ads in admin too. Only after changing the vars manually in the database i saw the jobads on page and in the admin menu - but there i cant activate oder deactivate the jobs as before.
