thank you for the help so far, but i am still having some issues. i checked my config file and it was showing the right values so thats not the issue, and i tried entering in the php values into my .htaccess file but when i enter it after my current .htaccess input i get an internal error 500 for all of my pages, and if i enter it withing what i currently have i see no changes. this is the only thing i have in my .htaccess file right now as without this, the profile extentions (ex. mypage.com/bob see more wasn't being created and would come up with a page not found error) so here is all that is in it now:

<IfModule mod_rewrite.c>
RewriteEngine on

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule .+ - [L]
RewriteRule ^([A-Za-z0-9_-]+)$ profile.php?ID=$1 [QSA,L]
</IfModule>

Is there something i am doing wrong, or are there different headers/footers i should be using around the php values in my .htaccess

thank you!
