Help with access to folder outside of WP

Hello everyone. I’m very new to WordPress and still trying to figure it out. I just converted my site (www.airbornimaging.com) to WP and have it installed in a separate directory (/site) other than my root. My problem is that I have another folder (/gallery) that I am unable to access directly. If I type in the address it gives me a page not found error.

I’ve researched this a bunch and have tried editing my .htaccess file in my root folder with no luck. If I turn RewriteEngine Off I’m able to access the /gallery folder but my site becomes broken…only allowing me to view my main page and none of the others (404 error).

Here’s my root .htaccess file:

# BEGIN WordPress

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /site/
RewriteRule ^index\.php$ – [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /site/index.php [L]
</IfModule>

# END WordPress

Thanks for any help with this matter.

Tom
