I’m having the same issue in Chrome. My contact form is hidden on the page and comes up in a lightbox. When I try to submit the form, I see the 403 error in my Web Inspector, the 403 error is for
/?_wpcf7_is_ajax_call=1&_wpcf7=4&_wpcf7_request_ver=1423085976327
Actually, the issue resolved itself after I ran all the pending plugin/core updates on my site!
Turns out it now works in Chrome and IE, but I’m getting this error in Safari and Firefox.
Any other fixes for this? I’m getting the same thing.
IIRC I worked around this by moving the form from a div on the page to its own page and just calling it in an iframe lightbox. It’s more time consuming as you need to pull in all your site assets, but at least it works.
