switching project information type to proprietary gives error

Do you really want to hide your entire project from the world? Setting the Project to Proprietary means only the people you share with will ever see it, and you will be limited with what you can do. A Proprietary project cannot ever contain public data. Anything that Lp does not support as Proprietary must be deleted/removed before the project is made Proprietary.

To have total confidentiality, you must first remove all public data from the project:
A. Disabled Launchpad Answers support tracker as the page warns:
   Visit https://launchpad.net/numerink , Choose "Configure support tracker" and
   set it to "Unknown" or "Not Applicable"
B. Make all Public blueprints Proprietary
   For each blueprint listed on https://blueprints.launchpad.net/numerink/+specs?show=all
   Change the Information type to Proprietary
C: Make all bugs Proprietary
    For each bug shown on https://bugs.launchpad.net/numerink/+bugs?field.information_type%3Alist=USERDATA&field.information_type%3Alist=PRIVATESECURITY
   Change the Information type to Proprietary
D. Configure Branches
   I suspect you have pushed branches to lp, but not told Lp which one belongs to
   the projects focus of development series. You need to do that so that you can see
   all the branches your project has.
E. Make all branches Proprietary
    For each branch shown on https://code.launchpad.net/numerink?field.lifecycle=ALL
    Change the Information type to Proprietary

Thanks a lot. I've done all the above but I still get a message stating that I have questions and bugs that aren't proprietary or embargoed. It's very confusing

Any extra help would be appreciated

You asked this test question on your own project. Invalid questions are excluded from the default searches
    https://answers.launchpad.net/numerink/+question/208787

Questions cannot be deleted...they are always public. You might be able to change the project it is for. Try obsolete-junk

Also, I can see a team is an answer contact for the project
    https://answers.launchpad.net/~numerink-team/+answer-contact-for

Closed bugs are excluded from the default searches. The search for all non-proprietary bugs might show them:
    https://bugs.launchpad.net/numerink/+bugs?field.status%3Alist=NEW&field.status%3Alist=OPINION&field.status%3Alist=INVALID&field.status%3Alist=WONTFIX&field.status%3Alist=EXPIRED&field.status%3Alist=CONFIRMED&field.status%3Alist=TRIAGED&field.status%3Alist=INPROGRESS&field.status%3Alist=FIXCOMMITTED&field.status%3Alist=FIXRELEASED&field.status%3Alist=INCOMPLETE_WITH_RESPONSE&field.status%3Alist=INCOMPLETE_WITHOUT_RESPONSE&field.information_type%3Alist=USERDATA&field.information_type%3Alist=PRIVATESECURITY

Thanks again!!
That definitely showed more bugs. I've managed to remove answers properly with that info.
As far as bugs go I've removed all of the ones from your link but have also removed bugs from my series by adding it to the url .../numerink/series/+bugs... This showed a few stray bugs that were'nt linked to the project.
Did the same with all team members present and past and team as well. Found a couple more bugs.

But I still get an error when I try to make the project proprietary, it is still saying that I have some non-proprietary bugs.
Any idea where the missing bugs might be? Thanks!!

Maybe making all these proprietary automatically would be a nice addition. I've had to manually change a lot of bugs and it's not even a big project. I can imagine some people pulling a lot of hair out. :)

ok I got it working. Seems like I missed a few dyplucate bugs for some reason. I found some by going into the sharing options. And found some through the bug search by ordering by status (they wouldn't show if I filtered by privatesecurity)

So now it's all good. Thanks again!!
