The left navigation menu disappeared from my SharePoint 2019 servers (2 Web Front Ends and 2 SQL Back Ends, all with the latest OS, SharePoint, and SQL patches) recently. I've tried the following:
- Create a new Site Collection in the existing Web Application
- Create a new web application and a new site collection within it
All show the same issue.
For reference, I've placed a screenshot below showing the blank left nav. To generate that screenshot, I created a new web application, created a new site collection in it (team site) and nothing else.
I welcome ideas as I am new to SharePoint 2019. Thanks!
