I have been but I deleted that post due to finding another method of posting by mail. I love jetpack and will definitely be using its functions for other things but since it wasn’t a simple reinstall of the plugin I had to find an alternative way. Thank you for your support and quick response but I don’t think there is a point in trying to fix it now.
Not sure what changes actually made this happened. It sadly happened over a number of days and yes I have tried to change the email.
