I can see that some widgets changed positions in the result of theme changing. Sorry for the inconvenience, you can place widgets in right positions (Appearance > Widgets) from Inactive Widgets area.
If it does not work with the default theme, this means that the problem doesn’t relate to the theme and can’t be fixed from our side. I would recommend you to contact hosting provider or plugin author to fix the problem with email sending.
