Wordpress and Magento Installed On Same Server Issue - php

Question

I have installed wordpress into the root of my domain. After that was already done and setup, we decided to install Magento into a subfolder called shop. The problem that I am having is that on certain pages in Magento, actually just the checkout page, pages are carried over from wordpress. If I am logged into wordpress, my wordpress menu loads into the Your Checkout Progress box. If I am not logged in, the wordpress login page loads to the right of the checkout. I have tried to prevent this by using my .htaccess in the root of the hosting with the following
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteCond %{REQUEST_URI} "/shop/"
RewriteRule (.*) $1 [L]
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
Here is my Magento .htaccess file

I am starting to think that I might have to find a way to move the WP install to another folder unless someone has any suggestions.
UPDATE:
Here is a link to a screenshot of what I am seeing, per the requests in the comments.

Answer 1

I think, in your Magento .htaccess, you need to remove the following section
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /shop/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /shop/index.php [L]
</IfModule>
and uncomment the following line.
#RewriteBase /shop/
