I just upgraded to version 3.8 and now e-mail submissions on all the forms I'm using on my site have stopped working. I'm currently using three plugins - Form Maker, Jetpack and Big Contact. None of these work anymore - the e-mail does not get delivered when I click on Submit on the site. I changed the e-mail address in all forms to Gmail and that too does not work. The mail does not get delivered.
I have re-installed all the plugins, but that does not help.
Can someone here please give more details regarding this.
