ServiceNow Australia Release 2026: How to Fix Info and Error Messages After Upgrading to the

ServiceNow Australia Release: Error and Fix

ServiceNow Australia Release: After upgrading to the ServiceNow Australia release, some instances may show info and error messages in the wrong position, especially when modal windows are used. In affected cases, messages can appear behind the modal or become difficult to dismiss, which impacts usability and can confuse end users.[support.servicenow]

Issue

The issue typically appears after an upgrade when notifications such as info messages or error messages are triggered from a form, UI action, or modal-based interaction. ServiceNow has documented a related problem in which info and error messages are displayed under modal windows rather than above them.[support.servicenow]

Users may notice one or more of the following behaviors:

• Info messages appear behind a modal window.[support.servicenow]
• Error messages are not clearly visible to the user.[support.servicenow]
• The dismiss option may be harder to access when the message is rendered below the modal layer.[servicenow]
• The issue is more noticeable in modal-driven workflows after the Australia upgrade.[servicenow]

Cause

The root cause is related to the notification container layering in the user interface. ServiceNow states that modal windows do not currently have their own notification container, which causes notification messages to render beneath the modal in some scenarios.[support.servicenow]

This behavior is documented as a known product issue and enhancement-related limitation. ServiceNow also identifies the related problem record as PRB1332321 in its knowledge article on messages displayed under modal windows.[support.servicenow]

Resolution

A practical workaround is to update the page-level CSS so the notification container displays above the modal layer. ServiceNow’s published workaround is to increase the z-index of #uiNotificationContainer.[support.servicenow]

Use the following CSS:

css#uiNotificationContainer {
  z-index: 10000;
}

Add this CSS to the page or UI context where the modal is being used. In environments using Service Portal, ServiceNow’s documented workaround is to open the affected page and place the CSS in the Page Specific CSS field.[support.servicenow]

Steps

1. Identify the page, form, or portal page where the modal window is used and where messages are not displaying correctly.[support.servicenow]
2. Open the affected page configuration in ServiceNow.[support.servicenow]
3. Add the CSS rule for #uiNotificationContainer with a higher z-index value.[support.servicenow]
4. Save the changes and test the same scenario again after clearing cache if needed.[support.servicenow]
5. Confirm that info and error messages now appear above the modal and can be dismissed normally.[servicenow]

Best practice

Before applying the fix in production, test it in a sub-production or development instance that has already been upgraded to Australia. ServiceNow recommends reviewing release notes and known fixes for the Australia family so upgrade-related UI issues can be validated early.[servicenow]

It is also useful to review related notification behavior in Next Experience and verify whether notification preferences or workspace-specific UI behavior are contributing to the issue in a custom implementation. ServiceNow provides separate documentation for notification preferences in Next Experience.[servicenow]

How to Fix Info and Error Messages After Upgrading to the ServiceNow Australia Release

After upgrading to the ServiceNow Australia release, some instances may display info and error messages incorrectly when modal windows are used. In these cases, the messages can appear behind the modal instead of above it, making them difficult for users to read or dismiss.[servicenow]

This issue is caused by notification container layering in the user interface. ServiceNow documents a related known issue in which modal windows do not have their own notification container, which can cause info and error messages to be displayed under modal windows.[support.servicenow]

To resolve the issue, add the following CSS so the notification container appears above the modal layer:[support.servicenow]

css#uiNotificationContainer {
  z-index: 10000;
}

If the issue occurs in Service Portal, open the affected page and add this code to the Page Specific CSS field. Then save the change and test the message behavior again.[support.servicenow]

After the update, info and error messages should appear in front of the modal window and be easier for users to view and dismiss.[support.servicenow]
