We launched a petition without realizing the impact of having the "Ask to publish actions to stream" box unchecked in our site settings. Now we're 150 signatures into the petition, and realized the signer names are not appearing in the petition stream. I've tried to uncheck the "Don't publish this on website" option within the individual signature pages, but when I click "update signature" a Nationbuilder error page appears: "Looks like one of our pipes burst a leak. Sorry about that. We've been notified about this issue and will look into it shortly." Is there any way I can make this change in the already existing signatures?
