Can't access install screen

I followed all of the instructions to install Omeka, but when I go to http://mydomain.org/omeka, it just loads my normal website. I tried adding /index.php to the URL and it redirected me to /omeka/install, but still just loaded my normal website. Any ideas on what I am doing wrong?

Sounds like there might be some conflicting .htaccess rules from your normal website.

Often, simply adding RewriteBase /omeka/ into the .htaccess for Omeka is enough to overcome the rules conflicts.

Thanks-I tried that and no luck. Any other thoughts?
