Okay lets see if this sheds any light:

here is the htaccess file from my root:

RewriteEngine On

RewriteCond %{http_host} ^travel-writers-exchange.com

RewriteRule ^(.*) http://www.travel-writers-exchange.com/$1 [R=301,L]

# BEGIN WordPress

<IfModule mod_rewrite.c>

RewriteEngine On

RewriteBase /

RewriteCond %{REQUEST_FILENAME} !-f

RewriteCond %{REQUEST_FILENAME} !-d

RewriteRule . /index.php [L]

</IfModule>

# END WordPress

Here is the htaccess I would put in my /Forum directory, if it didn’t trigger the 500 error

<IfModule mod_rewrite.c>

I’ve verified that there are no errant spaces or line breaks……it doesn’t look to me like there are syntax errors or conflicts, but I’m no expert……
