Highlighter Markup not deploying to WordPress site due to 401 error

The Schema App WordPress plugin relies on the Schema App server for loading Highlighter markup. In some instances, the Schema App project dashboard may trigger webhooks and give 401 errors, preventing the Highlighter markup from deploying. 

If this is the case, the following steps need to be taken:

1. Confirm the Schema App plugin is up-to-date. If not, update the plugin in WordPress.
2. Confirm the license is active in the Schema App plugin settings. To do this, go to WordPress admin and select Settings > Schema App > Licenses. The license status must be active. Check Screenshot-1
3. Make sure the JSON REST API has not been disabled for your WordPress site. This can be done by following the instructions in the article How to Disable JSON REST API in WordPress.
