Huh? So if they are logged in and the static pages alway tells them they are logged out, but the dynamic ones tell them they are logged in, you think that is working? It may be 'cosmetic' but it makes the plugin a nightmare, and it is BROKEN. Also, users can't log in through Links on mine - even if I use exactly the same details on the vBulletin log in. Nor does the registration via Links appear to work properly.
You shouldn't be offering it as a mod if it doesn't work properly.
Surely if it is just cosmetic, it won't be hard to fix or offer a patch solution? Please?
