karsho on "[Plugin: Contact Form 7] contact form 7 is not redirect"

I'm using Contact form 7 Plugin 3.5.2. When i'm submitting form, mail is going correctly. But no redirect is working. I mean, ajax-loader is showing upto refresh, no message is showing.

Same thing, when I click submit without type any field. No Error massage is showing.

If i logged in Wp-admin, then it's working fine. I don't know to solve. Help me, ASAP.
