How to Troubleshoot a SharePoint List Opening a Custom ASPX Page

Product: SharePoint Online
Device & OS: not provided
Scenario: A user inherits a SharePoint list configured by a previous administrator and needs to edit list items, but standard forms are not loading.
Observed behavior: Clicking a list item opens a custom ASPX page located in the Site Pages library with the List ID in the URL, rather than a standard SharePoint, InfoPath, or Power Apps form.

Before you start

Ensure you have Site Owner or Full Control permissions on the SharePoint site to access List Settings and modify form configurations.

Solution 1Recommended

Review SharePoint List Form Settings

Check the default form configurations to see if a custom form like InfoPath or Power Apps has been applied and overridden the default interface.

Often, developers customize list forms using Power Apps or InfoPath. If these are disconnected or customized heavily, they might route users to a different ASPX page.

Access List Settings

Navigate to your SharePoint list, click the Gear icon (Settings) in the top-right corner, and select 'List settings'.

Open Form Settings

Under the 'General Settings' column, click on 'Form settings'.

Verify Default Form Selection

Check if 'Use a custom form created in Power Apps' or 'Customize in InfoPath' is selected. To revert to the standard behavior, select 'Use the default SharePoint form' and click OK.

App Integrations: If the form settings look normal, check 'Site Contents' to see if a custom third-party app was installed that matches the list name and governs its behavior.

Solution 2

Inspect Column and View Formatting Customizations

Identify if custom JSON code has been applied to the list view or columns to redirect clicks to a custom ASPX application.

Frequently Asked Questions

How do I restore the default SharePoint list form?

Navigate to the list, click the Gear icon > List settings > Form settings. Select 'Use the default SharePoint form' and click OK to remove any custom form overrides.

Why does the list item open a URL in the Site Pages library?

This usually indicates that a previous developer created a custom SharePoint Framework (SPFx) web part or application hosted on a Site Page. The page reads the List ID and Item ID from the URL parameters to display a customized interface.

Can deleting the custom ASPX page fix the issue?

Deleting the custom ASPX page will break the link if the list view is still configured to redirect to it. You must first remove the redirect mechanism (like view formatting or app integration) before removing the ASPX page itself.
