Re: (Installation Problem) Help , it’s gone all wrong!
If you deleted everything in your root WordPress folder, you’re going to have to reinstall WordPress first, then your theme and plugins. That would be the first step, well before installing bbPress.
For the record, bbPress should be in a subdirectory of your WordPress installation if you’re going to try and integrate it.
So maybe you have your WordPress at /var/www/goldfiinger/home/, and if so, you would put bbPress at /var/www/goldfiinger/home/bbpress/.
