Am trying to use laravel to build a site but my routes all redirect to the homepage. Apache error logs show this

AH00124: Request exceeded the limit of 10 internal redirects due to probable configuration error. Use 'LimitInternalRecursion' to increase the limit if necessary. Use 'LogLevel debug' to get a backtrace.

And the .htaccess file is this

<IfModule mod_rewrite.c>
    Options -MultiViews
    Options +FollowSymLinks

    RewriteEngine On
    RewriteBase /

    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d

    RewriteRule ^(.*)$ index.php/$1 [L]
</IfModule>

The webroot has multiple sub-folders which are document roots for different domains. Am working with one of these sub-folders.

What is causing this error and how can it be fixed
