FAQs About Fixing SharePoint Not Finding Linked Aspx Files

Why are my linked ASPX files returning a 404 error even though they exist in the SharePoint Site Assets library?

This often happens if the ASPX files are not checked in or published as a major version. SharePoint requires files to be published before readers with limited access can view them or link them properly.

How can I verify that my custom ASPX page has the correct permissions for users to access the links?

Go to Site Contents, open the library containing your ASPX page, select the file, and click Manage Access. Ensure that your target audience has at least Read permissions granted at the item or library level.

Does enabling custom script at the site collection level pose a security risk when resolving ASPX link issues?

Yes, allowing custom scripts can expose the site to cross-site scripting (XSS) vulnerabilities. It is recommended to only enable this feature temporarily to fix the broken links or apply it exclusively to trusted administrative sites.

What should I do if the links inside the ASPX page still fail after renaming the file or moving it to a new document library?

You will need to update the relative URLs within the ASPX code itself. Open the file in a text editor or SharePoint Designer, correct the hardcoded paths to point to the new library location, and save your changes.
