Product: OneDrive Web
Device & OS: not provided
Scenario: Attempting to open the file options menu (the ellipsis) for various file types, including Word documents and PDFs, in the web version of OneDrive.

Before you start

Ensure you have your Microsoft account login credentials handy, as you will need to sign back into your OneDrive account after clearing your browser data.

Solution 1Recommended

Clear Browser Cache and Sign In Again

Clearing the web browser cache removes outdated or corrupted temporary interface files that trigger the React error on the OneDrive website.

This error is a known front-end bug in the OneDrive web application affecting multiple file types. In most cases, clearing your browser's cached data forces the browser to load the latest, error-free code from Microsoft's servers.

Open browser settings

Click the three-dot menu or settings icon in the top right corner of your web browser and select 'Settings'.

Navigate to browsing data

Go to the 'Privacy and security' section and click on 'Clear browsing data'.

Clear cached files

Check the box next to 'Cached images and files' (you can uncheck browsing history if you wish to keep it) and click the 'Clear data' button.

Sign in to OneDrive

Navigate back to the OneDrive website, enter your Microsoft credentials to sign in, and try clicking the ellipsis menu on a file again.

Server-Side Resolution: Microsoft has previously marked this widespread issue as resolved. If clearing the cache does not fix the problem, it may be a returning server glitch. In that case, you should create a new support thread on the Microsoft forums.

Frequently Asked Questions

What causes the Minified React error #31 in OneDrive?

This error is typically caused by a bug in the OneDrive web application's front-end code (React framework) or corrupted browser cache data that conflicts with the web page's scripts.

Are my files safe when this OneDrive error appears?

Yes, the Minified React error #31 is strictly an interface issue on the website. Your actual files, including PDFs and Word documents, remain safe and uncorrupted on Microsoft's servers.

What if clearing the cache doesn't fix the OneDrive error?

Try accessing your OneDrive account using a completely different web browser or open an Incognito/Private browsing window. If the issue persists across all browsers, the bug may be active on Microsoft's servers, and you should report it to Microsoft Support.

Can I still open my documents when this error occurs?

Yes. While the ellipsis menu might be broken, you can often still open documents by clicking directly on the file name, or you can access them using the OneDrive desktop sync client.
