I blog my art. And when I have a piece I just attach it in there. So I went to do that and it brought up the usual window where I can choose file from my computer, and then you hit upload, but it gives me a new window that says Vbulletin and tells me I'm not registered. Any ideas? Is this on my end, or EC's because it was working fine before. I can upload to albums still. Just not blogs.
No guarantees here, but I've seen this happen when the cookies for some reason get corrupted. I'd suggest deleting all of your EC cookies and then re-logging in and trying again. vB3 (the version we're using) does have some weirdnesses where it does lose track of cookies and logins sometimes for no apparent reason, and this sounds like that sort of circumstance.
