The requested URL /cdseopro.php was not found on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

Also tried removing everything from my .htaccess file but to no avail. I now have only this in the .htaccess file:

# ------------------------------------
# CDSEO Pro
# ------------------------------------
# This directory index is recommended to replace the
# x-cart default within this .htaccess file
DirectoryIndex home.php index.html index.php

# Enable mod rewrite engine
RewriteEngine On

# .htpasswd protection

# Remove # at the beginning of this line if your unable to access password protected folders:
ErrorDocument 401 "Unauthorized"

# Some servers require this Options directive to be disabled
# Remove # at the beginning of this line to disable:
#Options -Multiviews

# Some servers require the Rewritebase directive to be enabled
# Remove # at the beginning of this line to enable:
RewriteBase /

RewriteCond %{REQUEST_URI} !^/(payment|admin|provider|partner)/
RewriteCond %{REQUEST_FILENAME} !\.(gif|jpe?g|png|js|css|swf|php|ico)$
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-l
RewriteRule ^(.+)$ cdseopro.php
# ------------------------------------
# / CDSEO Pro
# ------------------------------------

Edit, even when I directly type in the URL to the cdseopro.php file in my browser I get a 404 error page, but this page is from the hosting company. I have contacted them if they know what's going on here...

May sound like a silly question, but are you sure that cdseopro.php was actually uploaded? If your host isn't able to figure out the issue please submit a support ticket with FTP information.
