Guest Writer Oct 8, 2026 870 views

Question details

The user needs to fix an issue where clicking a SharePoint site logo directs them to a JSON response instead of the site's modern home page.

Product: SharePoint Online
Device & OS: not provided
Scenario: Navigating back to the site's home page by clicking the SharePoint site logo when a modern site page is configured as the home page.
Observed behavior: Instead of rendering the SharePoint site home page, the browser opens and displays a raw JSON response.

Before you start

Ensure you have the exact URL of the affected SharePoint site and note whether this issue occurs for all users or just specific accounts.

Solution 1Recommended

Test the Site in a Private Browsing Window

Use an Incognito or InPrivate window to determine if the issue is caused by corrupted browser cache or conflicting session data.

Browser caching issues can sometimes interfere with how SharePoint modern pages render. Testing in a private window is the fastest way to isolate local browser issues from backend SharePoint configuration errors.

Open a Private Window

Launch your web browser and open a new InPrivate window (Microsoft Edge) or Incognito window (Google Chrome) using the browser's menu or keyboard shortcuts (Ctrl+Shift+N).

Log in to SharePoint

Navigate to your SharePoint site URL and log in with your Microsoft 365 credentials.

Click the Site Logo

Click the SharePoint site logo in the top navigation bar to see if it successfully redirects to the modern home page or still displays the JSON response.

Test the Site in a Private Browsing Window

Organization Policies: If your organization disables private browsing, try clearing your browser cache and cookies entirely, or test using a different web browser.

Solution 2

Submit a Support Request via Microsoft 365 Admin Center

If the issue persists in a private window, it is a backend routing issue requiring Microsoft Support intervention.

Frequently Asked Questions

Why does a JSON response appear instead of the SharePoint web page?

This usually happens due to a backend routing glitch in SharePoint Online. When a modern site page is set as the home page, the server may fail to render the user interface correctly upon redirect and instead outputs the raw API data (JSON) used to load the page.

Can I manually change the link associated with the SharePoint site logo?

No. By design, SharePoint Online does not provide an out-of-the-box setting to customize or change the URL that the site logo points to; it is hardcoded to redirect users to the site's default home page.

What is a HAR log and why does Microsoft Support need it?

A HAR (HTTP Archive) log records the exact interactions between your web browser and a website's server. Microsoft Support requires this file to diagnose network requests, API responses, and specific server-side errors that cause the JSON page load issue.
