@Shampa, Usha, actually, it might be due to the fact that the author wishes to publish it on his or her own blog or some other paying site. As you know, articles on boddunan are supposed to be exclusive and do not permit that content even on author's own blog. So I think it must be that!

Now the doubts are totally clarified

The article was unpublished as it was not having enough content to show on the site.

@Gulshan, you still can see the article as you are editor. Others cannot see it.

Is there any technical glitch going on with article publishing  and submission. I am not able to save or submit my article. Getting the same warning "Empty solutions not allowed" again and again. I am sure that i am sticking to the submission guidelines. I never faced such issues in the past

I too did not face such a situation earlier.

Clarification given by Maveric and Kalyani are quite convincing and gave me the real picture.
