OK, so I have found the solution. It turned out that there was a conflict in my js file. I had an animation that was initiated on pressing the submit button. I just had to get rid of the animation on submit button and voilea:) Everything works just fine!

Same problem here. Checked on v2.9.1 and v2.8.5. On the first one everything hangs on pressing the submit button. In 2.8.5. it also hangs but the email is sent nevertheless. I checked it on new installation and with plugins with database lg set to once latin II and once to utf8. No change.
If anybody has the same problem or knows how to resolve it just post it here.
