Exploring this mod a little further....
It was originally written for SMF 1.x.x and did everything it was supposed to do as alluded by earlier comments in this subject "View Only Boards". When a guest would try to enter a blocked area they would be redirected to a login register page.
For SMF 2.0.11 it does work as intended. The settings all are functional. The only difference is that the guest gets redirected to a 403 "
Sorry, but you have no access to this page." Search engines pick this up, but it would be better if the guest was redirected to the original intent, that is to a login register page.
In the Configuration - General One may block Guest from complete forum with the resultant effect they are redirected to login register page.
In the change to SMF 2.x.x it appears everything works as intended
Except the hook to go to the login register page has changed to a 403 Error page.

Anyone Any ideas how to correct this?
