Verify Site Administrator Permissions and Restore Missing Pages

Use the SharePoint Admin Center to grant yourself proper access, navigate to the hidden Site Contents page, and restore the missing Home page or index.aspx from the recycle bin.

This error typically occurs when the default home page (like index.aspx) or its containing Site Pages library is accidentally deleted or moved. You must first ensure you have the highest level of access to the site to view hidden files and the recycle bin.

Grant Site Administrator Access

Log in to the SharePoint admin center. Navigate to 'Active sites', select the affected site, and click on 'Membership'. Add your user account as a site administrator.

Access the Site Contents Page

Open a new browser tab and manually enter the site contents URL by appending '/_layouts/15/viewlsts.aspx?view=14' to your base SharePoint site URL (e.g., https://yourdomain.sharepoint.com/sites/yoursite/_layouts/15/viewlsts.aspx?view=14).

Check the Site Pages Library

In the Site Contents list, look for the 'Site Pages' library and verify if your Home page (usually index.aspx) is missing.

Restore or Recreate the Home Page

If the page is missing, click on 'Recycle bin' in the top right or left navigation menu. Select the missing page and click 'Restore'. If the page cannot be found in the recycle bin, you will need to create a new page and set it as the site homepage.

Verify Site Administrator Permissions and Restore Missing Pages

Verification Step: After restoring the file, manually type the URL of the index.aspx file into your browser to verify that it loads correctly before testing the main site URL.

Frequently Asked Questions

Why did my SharePoint home page suddenly disappear causing a File Not Found error?

A home page often disappears if it was accidentally deleted by a user with editing permissions, moved to a different document library, or if the permissions for the Site Pages library were altered.

How long do deleted files stay in the SharePoint Recycle Bin?

By default, deleted items are retained in the SharePoint Recycle Bin for 93 days. During this period, site administrators can easily restore the files to their original locations.

What should I do if the missing SharePoint page is not in the Recycle Bin?

If the page is not in the first-stage user Recycle Bin, scroll to the bottom of the Recycle Bin page and click 'Second-stage recycle bin' (accessible only to site admins). If it has been purged from there as well, the page is permanently deleted and must be rebuilt.
