Hi,
Thanks for your suggestion.
I removed the quotation marks “” from my subject in the mail tab. I also did as you suggested and deactivated all active plugins and changed to a WP default theme (I changed to Classic version 1.6 theme by Dave Shea). I then reactivated CF7 and copied the shortcode over to this link.
I did a test of the contact form: typed my name, my secondary email and a few random words in the subject and message. I hit send and it had the same problem. It is forever pending and won’t submit. I’m quite lost on what to do.
Is it possible to use a different contact form plugin? Or is there still some other way to fix it?
