SuiteCRM: How to Disable TinyMCE HTML Editor/Rich Text on Case Description Module

If you have a SuiteCRM installation, you may be wondering how to disable the rich text/TinyMCE editor on a field. We had this problem with the “Description” and “Updates” field for the case module. Here’s how to do it!

1. Create empty file at custom/Extension/modules/Cases/Ext/Vardefs/customizations.php
2. Add following lines to file
   1. unset($dictionary[‘Case’][‘fields’][‘description’][‘editor’]);
   2. unset($dictionary[‘Case’][‘fields’][‘update_text’][‘editor’]);
3. Do quick repair and rebuild from admin menu
