Fishpig: Autologin not working authentication exception because of index.php

Question

I have Fishpig Wordpress Integration installed along with Magento CE 1.702.

Wordpress is set up like this :

Database
    Charset                              utf8
    Table Prefix                         wp_
integration
    Integrate Theme                      Yes
    Home URL                             blog
    Path                                 wp
    Single Store                         no

I removed index.php from the frontend using this rewrite rule :

`<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>`

The problem is the Fishpig Wordpress autologin has stopped working with the error:

Unable to login. Check your WordPress Admin login details below.

I contacted Fishpig support and they said :

You need to configure your Magento installation not to use index.php.

I removed index.php from the admin area like this :

    RewriteRule ^index.php/admin/(.*)$ /my-admin/$1 [L,R]

This didn't fix the autologin problem and I noticed that the autologin button url contained the index.php so I removed index.php in the wordpress .htaccess like this :

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /wp/
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /wp/index.php [L]
RewriteRule ^/wp/index.php/(.*)$ /wp/$1 [L,R]
</IfModule>

This removed the index.php from the admin url but not in the autologin button

http://dummyurl.com/index.php/admin/wordpress/login/key/72a947f0e9452bfd6e92258d31ce7cd2/

I have been searching and wrecking my head with this, any help is appreciated.

To get the auto-login functionality working, you only require the default content in your .htaccess file and do not need to add any custom code in here. The following is all you need:

# BEGIN WordPress
<IfModule mod_rewrite.c>
  RewriteEngine On
  RewriteBase /wp/
  RewriteRule ^index\.php$ - [L]
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteRule . /wp/index.php [L]
</IfModule>
# END WordPress

It would help if you included the actual URL to your Magento site, as this would very quickly answer a few questions.
