Okay so these are your options:
1. Delete your browser history in the settings of your browser. Then, visit the site typing this:
http://congovibes.com/index.php Your phone will save the new address of the site and from that moment when you start typing "congovibes" it will take you to the proper place.
2. If you don't want to clear the history because you need the places where you are already logged in, type
http://congovibes.com/index.php all the time you visit the site. After a while your browser will forget the previous ip address, will save the new one, so from that moment you only need to start typing 'congovibes...' and it will take you to the proper place automatically.
Make sure you type the http... part. The forum is on http, not https, the browser automatically want to take you on https if you don't type http, that's why you see the 'your connection is not private message'. But if you clear your history, you only need to type the long address once, from that moment the browser will save it and use that when you start typing 'congovibes...'
This is how the internet borwsers work recently. It is not very good for old sites like Congovibes. So you need to use these solutions.
