Thanks for the update.
Upgrading to this version has caused an issue; when posting using the Quick Reply, it seems that it cannot use AJAX and therefore the standard redirection page (Thank you for posting! You will now be taken to your post. If you opted to post a poll, you will now be allowed to do so.) comes into play.
When I disable this product, this issue goes away.
So obviously, your product seems to be at fault.
I really hope it can be fixed
