Known Issue: White Left Navigation Panel and Missing Edit Button in SharePoint 2019

Issue:

We're currently aware of two issues affecting SharePoint 2019 environments:

Navigation Panel Problems

The left navigation panel may display incorrectly in one of two ways:

• Missing navigation: The panel appears as a blank white space instead of showing navigation options
• Unwanted navigation: If you've hidden the panel, it may unexpectedly appear as a blank white space and cover your page content

Missing Edit Button

The edit button is not appearing where it should be accessible.

The issue occurs across SharePoint 2019 sites, with or without ShortPoint.

Reason:

Our team investigated the issue and found that most affected users experienced it immediately after the recent SharePoint 2019 update (Core update KB5002754).

Actions to take:

If you are experiencing this issue, you may take the following actions:

For both problems: Connect with Microsoft SharePoint Support

To resolve both navigation and edit button issues, we recommend contacting Microsoft SharePoint support for guidance.

For navigation panel issue: Add custom CSS code in Theme Builder

We have a workaround to resolve the navigation panel issue on SharePoint 2019 sites that have ShortPoint installed. Follow the steps below:

• Launch ShortPoint Theme Builder

• Go to Utilities

• Select Custom CSS

• Copy the custom CSS code

Copy this code:

[class^="deferredLeftNav_"][class*="nav_"] {
  display: none;
} 

• Paste the code in the Custom CSS field and hit Apply

• Publish your changes

Important: This workaround does not resolve the issue with the missing edit button. Please reach out to Microsoft SharePoint support for this issue.
