Robots text, wordpress - block directory

Question

Hello, In my robots.txt i have this:

Disallow: /lo

lo is a directory with a script i want blocked.

Problem is that "Disallow: /lo" blocks a post of mine:

/lonely-cars-etc/

How shall i block lo directory corectly?

Please, take a look at my robots.txt. Maybe there are other problems i don't know about.

User-agent: *

Disallow: /bin
Disallow: /cgi
Disallow: /cron
Disallow: /lo/
Disallow: /stats
Disallow: /portfolio.html

Disallow: /wp-admin
Disallow: /wp-includes

Disallow: /*.xlsx $
Disallow: /*.doc$
Disallow: /*.pdf$
Disallow: /*.zip$

# Google Image
User-agent: Googlebot-Image
Disallow:
Allow: /*

P.S. On webmastertools i get this: Is this right?

http://www.site.com/wordpress-post/
Allowed Detected as a directory; specific files may have different restrictions

Not sure it's write for a wordpress page to be detected as a directory! Any opinions?

Thank you!

Answer 1

The only thing that I can suggest you is to manually allow the post:

Allow: /lonely-cars-etc/

Hope it helps.

Answer 2

I have to use /lo/ instead of just /lo

Answer 3

Googlebot supports using $ to specify end of line, so you should be able to use the following:

Disallow: /lo$
