Hello
have added filtering to it to force it to be text only
- maybe this is overly aggressive
will change it to allow again according to current user Joomla TEXT filters (e.g. super user is allowed safe HTML)
Edit
administrator/components/com_flexicontent/models/forms/field.xml
find line:
<field name="description" type="textarea" cols="30"
change to:
<field name="description" type="textarea" [b]filter="JComponentHelper::filterText"[/b] cols="30"
