While trying to flag the following:

I get an error page telling me I don't have the privileges to do so. I flagged some other pages and they went through fine.

I see the same too.

John A, you do not have permission to access this page. This could be due to one of several reasons:

1. Your user account may not have sufficient privileges to access this page. Are you trying to edit someone else's post, access administrative features or some other privileged system?
2. If you are trying to post, the administrator may have disabled your account, or it may be awaiting activation.

(I've deleted the snippets in the meantime.)

I don't have that problem but things are really looking screwy.

Oh I think I know what's causing this :)

I bet it's the flux capacitor :icon_cheesygrin:

... And you would be right.
