To bring back menu button, add below css.

.navbar-default .navbar-toggle {
border-color: #ddd;
.navbar-default .navbar-toggle .icon-bar {
background-color: #888;

To remove Login with social or Email
go to resources/views/auth/login.blade.php
remove .panel-heading div

Backers mean individual man, if three payments come from one person, then it will count as 1 backer
