So, Here is what I did!
I transferred a new domain(from godaddy) to my host(ipage). Both of the domains were pointing to home directory and I was no knowing that.
So, I installed a fresh copy of WordPress on the domain that I transferred. And later, I came to know that a new copy of WordPress is made in both the domains because both were pointing on the same folder.
Now,
I can see my plugins and themes but not the comments and posts! :(
