Known Error: "404 Not Found" When Viewing Personal Web Page

If you receive an error when viewing your personal website, there may be a problem with your home page file.


When you attempt to view your personal website (hosted on your personal share on Datastore), you receive one of the following errors:

  • “The requested URL /~yourULID/ was not found on this server.”
  • “404 Not Found”
  • “The webpage cannot be found.”
  • “HTTP 404 Not Found”


This error can be caused by two things:

  • Your home page file is not named correctly. (the html extension included)
  • Your website files are not located in the web folder (all lower-case) on your personal Datastore share.

Home Page File Name

Make sure your home page file is named with one of the following:

  • index.html (recommended)
  • welcome.html
  • default.html

In Windows, you may not be see the entire file name by default. To make sure file extensions are being displayed, do the following:

  1. Within your personal share on Datastore, do one of the following:

    • Windows 7: Click [Organize] > [Folder and Search Options] > [View].
  2. Uncheck the option that says, Hide file extensions for known file types, and then click [Apply] > [OK].

    • Windows 8: Click [View] and remove the check mark next to File name extensions.

    • Windows 10: Select the [View] tab and place a check next to File name extensions.

This will allow you to view the entire name of your home page file, including the extension. The .html extension must be at the end of your file name. For example, if your file is named something like index.html.doc, change it so its name is just index.html.

The Web Folder

Make sure your website files are located in the web folder on your personal Datastore share. This folder must be named “web” in all lower-case letters (not “WEB” or “Web”), and it must be located at the top level of your personal Datastore share.

If you delete the web folder, you can simply create a new one. Make sure you name it “web” with all lower-case letters.


  1. Open your personal share on Datastore.
  2. Right-click on a blank area of the window.
  3. Click [New] > [Folder] (if in Windows 7 or 8), or [New Folder] (if in Windows 10).
  4. Enter web as the folder name.


  1. Open your personal share on Datastore.
  2. Click [File] > [New Folder].
  3. Enter web as the folder name.
