Question details

The user is unable to successfully register a new SharePoint hub site and associates existing content, experiencing missing news and images after changing a site's URL.

Product
Microsoft SharePoint
Device & OS
not provided
Scenario
Changing a SharePoint site URL or deregistering an old hub to register a newly created site as the hub.
Observed behavior
SharePoint news, images, and content do not appear or sync properly with the newly registered hub site.
Before you start

Ensure you have SharePoint Administrator privileges in the Microsoft 365 admin center before attempting to register or unregister hub sites.

Solution 1Recommended

Re-register the Hub Site and Wait for Synchronization

Deregister the problematic hub site and register it again through the SharePoint admin center, allowing adequate time for background synchronization.

When you change a SharePoint site URL or switch hub site associations, the backend services require time to update all linked content. Rushing the process can result in fragmented content display.

1
Access Active Sites

Log in to the SharePoint admin center, expand the 'Sites' menu on the left panel, and click on 'Active sites'.

2
Deregister Current Hub

Locate and select the site currently acting as the hub. Click the 'Hub' dropdown in the command bar and select 'Unregister as hub site'.

3
Register the Target Site

Select the newly created site (or the original site if you are reverting). Click 'Hub' again and choose 'Register as hub site', then follow the prompts to confirm.

4
Allow 24 Hours for Sync

Leave the site alone for up to 24 hours. Synchronization of news, images, and aggregated content across associated sites is not instantaneous and often takes a full day after a URL change.

Synchronization Delay: Do not attempt to deregister and re-register multiple times within a few hours, as this can reset the synchronization queue and further delay your content from appearing.

Frequently Asked Questions

Why are news and images missing after changing my SharePoint site URL?

Changing a site URL breaks existing links temporarily. SharePoint relies on timer jobs to rebuild search indexes and update hub site associations, which can take up to 24 hours to fully sync news and images across connected sites.

Can I re-register my old site as a SharePoint hub site?

Yes. As long as the old site is still listed under 'Active sites' in the SharePoint admin center, you can select it, click the 'Hub' menu, and register it as a hub site again.

How do I unregister a site as a SharePoint hub?

To unregister a hub site, navigate to the SharePoint admin center, select 'Active sites', choose the site that is currently a hub, click the 'Hub' dropdown in the top command bar, and click 'Unregister as hub site'.
