Unable to load any icons after changing routes

[Jiwon Yeom]

Hi i try to customize the menus from this amazing template,
but for some reason I couldn't load any icons and my customized logo img (in static folder).
I just fixed few lines of 'routes.js' and 'src/components/UIComponents/SidebarPlugin/index.js'.
could you help me to figure out the logic to load icons and give a hint to fix my messed up code?

// routes.js

import NotFound from '../components/GeneralViews/NotFoundPage.vue'
import DetailedView from 'src/components/Dashboard/Views/DetailedView'
import Dashboard from 'src/components/Dashboard/Views/Dashboard'
import Icons from 'src/components/Dashboard/Views/Icons'

const routes = [
  {
    path: '/',
    component: DashboardLayout,
    redirect: '/admin/detail'
  },
  {
    path: '/admin',
    component: DashboardLayout,
    redirect: '/admin/detail',
    children: [
      {
        path: 'dashboard',
        name: 'Dashboard',
        component: Dashboard
      },
      {
        path: 'detail',
        name: 'Detailed View',
        component: DetailedView
      },
      {
        path: 'icons',
        name: 'icons',
        component: Icons
      }
    ]
  },
  { path: '*', component: NotFound }
]

export default routes

// index.js

import Sidebar from './SideBar.vue'

const SidebarStore = {
  showSidebar: false,
  sidebarLinks: [
    {
      name: 'Dashboard',
      icon: 'ti-panel',
      path: '/admin/dashboard'
    },
    {
      name: 'Detailed View',
      icon: 'ti-user',
      path: '/admin/detail'
    },
    {
      name: 'Icons',
      icon: 'ti-pencil-alt2',
      path: '/admin/icons'
    }
  ],
  displaySidebar (value) {
    this.showSidebar = value
  }
}
const SidebarPlugin = {
  install (Vue) {
    Vue.mixin({
      data () {
        return {
          sidebarStore: SidebarStore
        }
      }
    })

    Object.defineProperty(Vue.prototype, '$sidebar', {
      get () {
        return this.$root.sidebarStore
      }
    })
    Vue.component('side-bar', Sidebar)
  }
}

export default SidebarPlugin
