Re: Do I need a new install? no comment form or working urls
bbPress does not create the .htaccess file. You have to manually create it with a text editor either on the server, on locally, then upload it. The file can contain one of two things:
1. Options +MultiViews
That script will generate the rules you need to put in your .htaccess file. Use this if the first option does not work.
If you cannot get permalinks working, just change the mod_rewrite line to false in your config, so you can at least use your forum until you get permalinks working.
$bb->mod_rewrite = false;
