When uploading an image to my aptly-named "Public" album tonight (using the http://pics.livejournal.com/manage/
page), I received the following error message:
Server Error: couldn't set upic security: 10
When I checked the album right after this, the image had successfully uploaded, but the security was private.
I did read this post
and I'm aware that there is a known problem with randomly private images. I just wasn't sure if this error message was part of that. :)
