Broken Admin UI

System Information
  • Strapi Version: 3.5.3
  • Operating System: Windows 10
  • Database: MongoDB
  • Node Version: 14.16.0
  • NPM Version: 7.6.1
  • Yarn Version: 1.22.4


I wanted to create a new Plugin using the generate utility.
So I created it and then rebuild the Admin UI using “strapi build”.

But after i started the dev server, the UI was broken as you can see in the image.
I tried to fix it by deleting the plugin and then rebuilding, but it didn’t help.

Maybe someone can help me fix this.

If you are using strapi build, that means you have installed strapi globally, we do not recommend using the global installed strapi.

Use the local one: yarn strapi build or npm run strapi build
Also, can you try to delete the .cache and build folders before building the admin ui.

Thx for the quick reply,

I tried both: deleting .cache and build and using the local yarn strapi build.
But unfortunately the result is the same as before.

Hi @R3mb0

Having the same issue, Did you by any mean get it fixed?

I tried using npm instead of yarn and for some reason it worked.
I don’t know why, so i can’t give you further explanation…

But maybe you can give it a try.
