Notice: Undefined offset: 1 in views_block_view() (line 519 of C:\xampp\htdocs\drupal7\sites\all\modules\views\views.module).

I have started getting the following error on my Drupal 7 installation:

Notice: Undefined offset: 1 in views_block_view() (line 519 of C:\xampp\htdocs\drupal7\sites\all\modules\views\views.module).

Some background:

The site was running fine on my localhost for the past few days. I was creating blocks to displays list of articles and image albums and to control their visibility on different pages. All of a sudden, I started getting the above error message. I though, one of my block view has caused to problem, so I deleted the recently modified block view. That did not solve the problem. One by one, I deleted all views, but still I get the error. I reinstalled the Views module but no luck.

Surprisingly, I get the error only on the home page and no other page. If I redefine a home page instead of using the default one, I start getting error on that page. I don't get the error on any other page.

Perhaps something has become corrupted? Any help to fix the issue will be appreciated.
