Starting from January 10, 2022, the cloud-based version of Spell Checker “WSC” dialog plugin for CKEditor 4 (WSC plugin further) was disabled for all types of users.

The end of life of the WSC plugin was announced in 2020. The main reasons for deprecation were the following: low security, limited capabilities, and fewer active clients. As a result, we decided to stop supporting the WSC plugin and put more efforts in developing other WSC products.
Users that added the WSC plugin to CKEditor 4 config.js file using the extraPlugins parameter or those who are still using CKEditor version lower than 4.16.0 with the plugin built-in by default may face an issue with the loading spinner.
