sidra

i added this pages navigation plugin in my blog but i have some issues, as google search engine is showing some pages like this

http://www.google.com/search?hl=en&rlz=1C1AVSX_enPK383PK383&q=www.prayfornathan.org/blog/page/83&aq=f&aqi=&aql=&oq=&gs_rfai=

http://www.prayfornathan.org/blog/page/83?p=cphyaxfbdwdvccs

why this string ”cphyaxfbdwdvccs” although it should be like this http://www.prayfornathan.org/blog/page/83 also in robots.txt i set disallow blog/page but search engine still showing these url with this type of ”cphyaxfbdwdvccs” random string in the url.

can you guide me how can i get rid from it

thanks
