my index page remove from google and sitemap.xml.gz is showing as below

Hi ,
I can not see my index page when seraching and from webmaster tools > Crwaler Access link and from Test robotos.txt tab link it is show a file as:

Text of http://newtransferfactor4life.com/robots.txt

and the text inside is;

User-agent: *
Disallow:
Sitemap: http://newtransferfactor4life.com/sitemap.xml.gz

my question is does this cause the issue my index page has been removed from google?
and if yes ,what can I do now?
appreciated for any help.

 

By using this search site:newtransferfactor4life.com on google, I found there are 16 pages indexed by google.
Robots.txt is OK, too.

 

That's strange, why your robots.txt disallow the crawler to your sitemap? Are you using wordpress?

 

Yes I am using Wordpress.
but I have another sitemap.xml file in my root directory and google in web master tools is showing the access to it.
is there any problem?
Regards
