# How to disable the WSC plugin in CKEditor 4?

On January 10, 2022, we disabled the Free version of WebSpellChecker (WSC) in a dialog that was provided as a plugin, integrated by default into [CKEditor](https://ckeditor.com/ckeditor-4/) 4 editor. This is the end-of-life of this product. Users that have added the WSC plugin to the CKEditor config.js file using the extraPlugins parameter or still using CKEditor lower than 4.16.0 may face an [issue with the loading spinner](/v6.12.0/troubleshooting/client-side/spell-checker-wsc-dialog-plugin-for-ckeditor-4-stopped-working-incessant-loading-spinner.md).

To remove the WSC plugin from CKEditor 4, add the following line to your CKEditor config.js file:

```javascript
config.removePlugins ='wsc';
```

Note, that the [WebSpellChecker Dialog plugin for CKEditor 4 for Drupal 8](https://www.drupal.org/project/ckeditor_wsc) was also deprecated. But still, you can use the SCAYT module instead <https://www.drupal.org/project/ckeditor_scayt>. Also, you can use [WProofreader SDK](https://demos.webspellchecker.com/wproofreader-ckeditor4.html) instead. It's not a native module for Drupal, it is a pre-built JavaScript component that can be added to the Drupal pages with the editor (where the spell check is needed).
