since a couple of days ago I'm having problems with the comments on my blog. The comment form is correctly shown but when I try to add a comment the subbmitting process redirect to my home page, so instead of the comment form my home page is displayed.
I've tried to use a simple theme as recommended in the Jetpack Support but the problem remains the same. With Jetpack desactivated the comments work again.
In the last week I haven't done any update or installation of new plugins.
Any idea what can be wrong?
Thanks in advance for your help
