FYI: I was using Contact Form 8 (the fork which fixed issues with checkboxes) — it has been abandoned in terms of development, and is not compatible with WordPress 3.0.

I have switched to Contact Form 7 2.3 and the issue has been resolved.

I will note, however, that my tables and graphic finesse doesn’t work with Contact Form 7 which is annoying.

To those who actually read this, Contact Form 8 has been abandoned — follow the instructions on Contact Form 8’s Plugin Site to switch back to Contact Form 7.

I have the exact same issue — ever since upgrading to WordPress 3.0 I have had this problem.

In my case, the e-mail sends, however the spinning arrow runs indefinitely. Users react by clicking ‘Submit’ dozens of times, all resulting in dozens of e-mails.
