If I save created view and visit the view page it showing only filter field I am new to drupal and I am trying to create view for my content type, I followed the steps using a tutorial but I am not able to see the preview of the created content view if I save and visit the view page it showing only filter field. Please help me. 

I have used the following method to create the view.

1) click on view and Add new name.

2) enter the name and in the show field selected the content then i specified my created content in type of field, and newest first in the sorted by field.

3) selected the table format.

4) added the fields of specified content with the help of search box where in i have given the content name so all related fields show up.

5) added the filter field from specified content.
I think you set  "age expose field  required" it cause in first load nothing show up till user enter something in filter.
try it with removing "Required" checkbox.
