+### Ignoring Errors
+
+When there's an error fetching or displaying a widgets data, then it will be highlighted in yellow, and a message displayed on the UI.
+
+In some instances, this is a false positive, and the widget is actually functioning correctly. If this is the case, you can disable the UI error message of a given widget by setting: `ignoreErrors: true`
+
+```yaml
+- type: gl-disk-io
+  ignoreErrors: true
+  options:
+    hostname: https://glances.dns-device.local
+```

 ### Widget Styling
 
 Like elsewhere in Dashy, all colours can be easily modified with CSS variables.
