I am trying to find everything I can both to make you mad and to help you, sorry if you see any errors caused by me in the logs.
Besides, when trying to access action=admin it asks me for the password twice, which is of course the double check when trying to access the admin section. It shouldn't be asking it in the first place as I'm not admin.
The back button, you say, does not take you back...
Well, how about telling us, where it does take you?
Nowhere. It refreshes the page. I am opening another topic because it happens not only with the action=admin but also action=moderate and I have the feeling it happens all over the place.
To be considered.
I think there are no security implications in exchanging the checks, but better have a second look.
Yeah I think that if you just switch the order it's going to be fine :)
