How to Fix a SharePoint Home Page 404 Error or DMS File Download in SharePoint Online
Question details
The user needs to restore access to a SharePoint site home page that displays a 404 error or unexpectedly downloads a DMS file because the original Home.aspx page is missing or unavailable.
- Product
- SharePoint Online
- Device & OS
- not provided
- Scenario
- A SharePoint site home page cannot be accessed; the browser shows a 404 error or downloads a DMS file instead of rendering the home page.
- Observed behavior
- The original Home.aspx page has been deleted or is unavailable, so SharePoint cannot render the site home page and returns a 404 error or DMS file download.
Before changing the home page, open SharePoint Online and confirm that you can access the affected site with at least Edit permission to the Site Pages or Pages library. Identify whether any existing site page is suitable to become the new home page.
Check the Site Pages Library and Set a Working SharePoint Page as the Home Page
Use this method first when the home page returns a 404 error or downloads a DMS file and another existing page is available.
SharePoint uses the Home.aspx file in Site Pages or Pages as the default home page. If that file was deleted or is unavailable, the site cannot render the requested home page and may return a 404 error or a DMS file download.
In SharePoint Online, select Site contents from the site menu, then open Site Pages or Pages.
Look for the Home.aspx file or the page currently marked as the home page. If it is missing, renamed, or corrupted, choose another page or create a new one.
Select the page you want to use, right-click it, and choose Make homepage. Confirm that the page now opens when you go to the site URL.
Create a New SharePoint Page and Make It the Site Home Page
Use this method when the original Home.aspx page is missing and no suitable existing page is available.
Use WPS Office to Open SharePoint and DMS Documents After Restoring Access
WPS Office cannot change SharePoint site settings, but it is a free, lightweight Microsoft Office alternative for opening and editing the documents you use from SharePoint or a DMS. It offers familiar tools and strong Microsoft Office format compatibility.
- 1. Download WPS Office: Go to wps.com and select Download WPS Office Free for Windows, Mac, iOS, or Android.
- 2. Install and launch WPS Office: Open the installer, follow the setup prompts, and launch WPS Office on your device.
- 3. Open documents from SharePoint or DMS: Use Writer, Spreadsheets, or Presentation to open and edit files you download or access from your SharePoint or DMS library.
Frequently Asked Questions
Why does my SharePoint home page show a 404 error?
The site home page is usually a file named Home.aspx in the Site Pages or Pages library. If that file is deleted, renamed, or unavailable, SharePoint cannot render the home page and returns a 404 error.
How do I set an existing page as my SharePoint home page?
Go to Site contents, open Site Pages or Pages, select the page, right-click it, and choose Make homepage. Then refresh the site URL to confirm that the page loads.
Can I restore the deleted Home.aspx page instead of creating a new page?
Check the SharePoint recycle bin and the page library version history first. If the file is not recoverable, create a new page and set it as the home page.
Why does SharePoint download a DMS file instead of opening the home page?
This can happen when the home page file is missing or is not being served as a SharePoint page. Restoring or replacing the home page usually stops the download behavior.
What permission do I need to change the SharePoint home page?
You need at least Edit permission to the Site Pages or Pages library. Site owners and users with Design or Full Control permissions can make the change.
