Views: Displaying the subgroup of current group

This article will create the simple view that will display the sugroups of current group.

Drupal form error message displaying on next page reload

Today while working I faced with very strange situation. On my theme I had displayed/rendered a block. I had displayed block on the welcome page and using following code.
