Duplicate  login required to view attachment, already logged in


Active member
I try to view the attachment in the threadbit bug report thread and it asks me to login to view the attachment. I am already logged in!

I was having this issue as well. The only way I got around it was to log out, then log back in but made sure to tick the "stay logged in" box.

In vBulletin I have seen this caused by cookie scoping issues. For example, you login from and browse the forum using "www" but the attachment is inlined using a different subdomain such that the login cookie is out of scope. Fixes in that situation include changing the URL or adjusting the cookie domain setting to work on the entire domain (.domain.com).

Just thinking out loud.
