title: Ignored PostCSS Plugin
---

## Why This Error Occurred

The project's custom PostCSS configuration attempts to configure unnecessary plugins:

- postcss-modules-values
- postcss-modules-scope
- postcss-modules-extract-imports
- postcss-modules-local-by-default
- postcss-modules

## Possible Ways to Fix It

Remove the plugin specified in the error message from your custom PostCSS configuration.
