I have installed everything, no errors, fixed the .htaccess file. Get "Pretty URLs" on my site, but when I click on them, get Not Found errors on the Pretty URLs. My base folder is /forum/. I uncommented the line in .htaccess file to account for this. I had this same problem when I was trying to work on a Mambo site and get the URLs looking good. Always get the Not Found error, so it must be something I am doing wrong. Any suggestions??
