what i did wrong? Help required

As am still beginner, always do mistakes, but all of my posts in my blog indexed in google, today i plated around the setting of all in one seo plugin, so it seems i changed something or disabled functions related to post so that not indexed.
Could any one here help provide me with all exact settings of this plugin?
All replies are highly appreciated.
Regards
