Form always redirecting to the same page when submit

Hi all,

I have use this plugin in all the web sites I worked. I used it for my current site as well (latest version – 4.6.1) with latest wordpress 4.7.2. But I am getting following error. Instead of Ajax submission it is redirecting the page and this hash “#wpcf7-f195-p4-o1” appending to the URL. If I fill correctly and submit mail is forwarding and all the functions working fine except this hash appending and page redirecting issue.

Why it is redirecting and appending the hash (form ID/action) to the current URL.

Thanks
