Gulp.js browser-sync not reloading my browser

Question

Gulp browser-sync is not reloading my browser. When I hit save on my project it builds everything fine. My browser blinks and says "Connected to Browser-sync" on the upper right hand corner. It does not load the changes though. When I manually hit refresh, on chrome, it will load the changes. I've been up and down the gulp file and can find nothing wrong. Any advice?

Gulp.js file:

    var $        = require('gulp-load-plugins')();
var argv     = require('yargs').argv;
var browser  = require('browser-sync');
var gulp     = require('gulp');
var panini   = require('panini');
var rimraf   = require('rimraf');
var sequence = require('run-sequence');
var sherpa   = require('style-sherpa');

// Check for --production flag
var isProduction = !!(argv.production);

// Port to use for the development server.
var PORT = 8000;

// Browsers to target when prefixing CSS.
var COMPATIBILITY = ['last 2 versions', 'ie >= 9'];

// File paths to various assets are defined here.
var PATHS = {
  assets: [
    'src/assets/**/*',
    '!src/assets/{img,js,scss}/**/*'

I was helped with the fix at zurb/foundation-sites on github by gakimball. There were issues with the gulp.js file for foundation 6.1.1. Github issue page: https://github.com/zurb/panini/issues/10#issuecomment-172692241 explains more. Replacing my gulp.js file with the following code fixed the issue.

New gulp.js:

    var $        = require('gulp-load-plugins')();
var argv     = require('yargs').argv;
var browser  = require('browser-sync');
var gulp     = require('gulp');
var panini   = require('panini');
var rimraf   = require('rimraf');
var sequence = require('run-sequence');
var sherpa   = require('style-sherpa');

// Check for --production flag
var isProduction = !!(argv.production);

// Port to use for the development server.
var PORT = 8000;

// Browsers to target when prefixing CSS.
var COMPATIBILITY = ['last 2 versions', 'ie >= 9'];

// File paths to various assets are defined here.
var PATHS = {
  assets: [
    'src/assets/**/*',
    '!src/assets/{img,js,scss}/**/*'
  ],
  sass: [
    'bower_components/foundation-sites/scss',
    'bower_components/motion-ui/src/'
  ],
  javascript: [
    'bower_components/jquery/dist/jquery.js',
    'bower_components/what-input/what-input.js',
    'bower_components/foundation-sites/js/foundation.core.js',

Thanks to the code above browser-sync is working again - Thanks gakimball!
