Page distorsioned

It seems that your theme is having conflicts with ThemeMyLogin. Try adding this to your child theme’s stylesheet:

label[for="user_login"], label[for="user_pass"],
#loginform, #registerform {
    float: none !important;
    margin-left: 0 !important;
}

If you don’t have a child theme you can use this plugin:
