Hi,
We have a contact form which redirects to a URL, this has been tested and worked great in all browsers until Internet Explorer 11 unfortunately the redirection crashes IE 11 even though the form sends through correctly.
My Additional Settings is set to:
on_sent_ok:"window.location.replace('https://www.url.com.au/thank-you/');"
Contact Form 7 is Version 3.5.4
Wordpress is 3.6
I can update these as necessary and put in any experimental fixes as I have a development environment up and running.
