Google doesn't index cause of my robots.txt

Hello everybody

I’ve got a Problem with the robots.txt.

My folder structur looks like this:
/domain/index.php
/domain/robots.txt
/domain/domainname/here are all the WordPress Files
/domain/domainname/robot.txt

If I want to index the Website the following error occurs:
due robot.txt declined

But I created robot.txt files on my own with follow content:
User-agent: *
Disallow: /wordpress_Bachmann3004/wp-admin/
Disallow: /wordpress_Bachmann3004/wp-includes/

Is it maybe a problem, that the WordPress Files are in a single Folder?

Thanks for your help!
