Open and use the web part maintenance page

The web part maintenance page in SharePoint Online or SharePoint Server 2019 is actually a "maintenance mode." While in maintenance mode, you can:

• View and copy the data and manifest information for each web part.

• Remove web parts you suspect are causing problems.

• Rearrange web parts.

Maintenance mode initially opens in a view-only state, but if you have edit permissions, you can remove and rearrange web parts.

Open web part maintenance mode

1. Go to the page for which you want to open web part maintenance mode.

2. In the address line of your browser, append ?maintenancemode=true to the end of the URL for the page. For example:

   https://contoso.sharepoint.com/teams/SitePages/Home.aspx?maintenancemode=true

On your page, you will see a summary of data from the Manifest and Data tabs. The summary information includes:

Alias	The name of the web part
Id	The unique ID of the web part
Instance Id	The ID of a specific instance of a web part (that is, if you have two more of the same web parts on a page, they will each have the same web part ID, but a different instance ID.
IsInternal	Indicates whether the web part was made by Microsoft or a third party. If True, it is made by Microsoft. If False, it is made by a third party.
Version	The version number of the web part.
Environment	Environment: Indicates the SharePoint environment in use. 0 = Test environment 1 = Local Workbench 2 = SharePoint 3 = Classic SharePoint
