AJAX response unable to be parsed as valid JSON object.

[Dipsy Doodle Doo]

I get this message every time I click submit:
"AJAX response unable to be parsed as valid JSON object."
I close that and click submit again and get:
"You already submitted this".
I close that and click submit again,
and my post posts.
Any idea what is going on?
Thanks!

But not this time. Maybe it has something to do with adding images?
edit:
No, got it again in preview:
"AJAX response unable to be parsed as valid JSON object.
Close"
Closed that and got:
"You've already submitted this form.
Close"
(Still in preview)
(clicking submit once again)
How can I fix this?
Thanks!

Thank you! I switched to a different browser and it stopped the problem.

I had been having the same problem for a week or so but today it started working properly again, WITHOUT me having to install a new browser, change my settings or pay for a membership.
