Where is the best place to get help regarding problems uploading photos to Google+, not for a post or message, but to my free storage via autobackup or manually from my desktop? Previously, uploads, automatic or otherwise (at "standard size" free) worked fine. Today I can no longer upload. I get "unknown server error." From this same desktop, I can upload photos to my wife's Google+ account. But as soon as I log out of her account, and into my own, uploads are impossible.
