## Describe the bug

I am getting a CSS break issue while routing from one link to another on client-side in production build only. In development build, it is working fine.

## To Reproduce

1. Go to this link http://ec2-3-134-112-176.us-east-2.compute.amazonaws.com:3000/english-test.
2. Click on header title Fluency Hub on the top left header.
3. You will get navigated to another page you can see the page with broken CSS.
4/ Now, refresh the page its CSS works well but after again repeating these steps gave issue only in the production build.
5. If you are cloning the repo then just clone the repo from this link https://github.com/geekyoperand/fluencyhub.git.
6. Now run the npm run start:staging for producing issue which will run a production build of next.js.
7. If you run just npm run start It will work well because it will run a development build.

## Expected behaviour
CSS must not get breaked while performing client-side routing in the production.

## Screenshots
after client side routing expected :
!image

after client-side routing current :
!image



## System information

- OS: macOS, Windows
- Browser : chrome
- Version of Next.js: 9.2.0

ребят а это норм что у меня при загрузке страницы в _app я вывожу в консоли path и сначала норм но вместе с url приходит "/_error" pathname. будто после app потом error срабатывает но на экране при этом ничего нет

и этот _erro только на определенной странице выскакивает)

Can anyone help me out with this?

hey man! yes, i try to help you. right now i clone you project and try to find problem

I already had this problem and I fixed it but I forgot how)

Okay great Thanks a lot man

hey man, i am clone thats repository. and all works fine, but i am see what u have'nt .babelrc u have bad format files, || add thats config/file

{
  "presets": [
    "next/babel"
  ],
  "plugins": [
    ["styled-components", { "ssr": true, "displayName": true, "preprocess": false } ]
  ]
}

кто нить чекал вообще его модули а то заклонил и ток потом подумал :D благо клонил на хреновый ноут с виртуалкой но всё же)

ну глобально же ты не ставил ничего?

конечно нет)

тогда не сцы))

So are you able to fix it after changing  .babelrc

{
  "presets": [
    "next/babel"
  ],
  "plugins": [
    ["styled-components", { "ssr": true, "displayName": true, "preprocess": false } ]
  ]
}

?

yes its wotk fine for me. just remove you node_modules and fully install you project

and remove dont used packages from package.json))

Still breaking when I run npm run start:staging

u forget reinstall packages?)

I run it after reninstalling packages but the page css still breaks
