I recently launched a new website on GoDaddy shared hosting. The website required mod_rewrite for SEO-friendly URLs. GoDaddy provides mod_rewrite but every time I tried to hit a two-deep URL, I would get a 404 error. Here's what I had:

# Mod Rewrite
Options +FollowSymLinks
RewriteEngine On
RewriteBase / 
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]

The fix to this problem was to add the following directive before my mod_rewrite directives:

#Fix Rewrite
Options –Multiviews

Tada! The URLs began working and the website's SEO has taken off!
