I find myself in a faintly ridiculous situation. I had some trouble setting up roles so that site authors could work with Nextgen so I set all the Nextgen roles temporarily to 'Anonymous'. The upshot of this is that the site admin is now blocked from doing anything on any of the Nextgen admin or setting pages. An anonymous user can't get to it because they're effectively blocked from any of the WordPress admin pages. So now nextgen is closed to everyone along with the means to open it back up to anyone.
Does anyone have any thoughts on this?
