Base44 Login Page Not Loading or Showing Blank Screen
After setting up user authentication in your Base44 app, the login page fails to load or displays a completely blank white screen. Users cannot access any protected pages and the entire authentication flow appears broken.
This issue frequently occurs right after enabling the built-in auth module or after making changes to page visibility settings. The browser console may show JavaScript errors related to the auth component failing to initialize.
In some cases the page partially loads but the login form fields never appear, leaving users stuck with no way to sign in to your application.
Error Messages You Might See
Common Causes
- The authentication module was enabled but the login page was not set as public, creating a redirect loop
- Custom CSS or a third-party script is conflicting with the Base44 auth component rendering
- The app's auth settings reference a callback URL that doesn't match the current deployment domain
- Browser cache is serving a stale version of the page from before auth was enabled
How to Fix It
Start by checking your Base44 app's authentication settings panel. Ensure the login page itself is marked as a public page so unauthenticated users can actually reach it. Look for any redirect URL mismatches between your development and production environments.
Try opening the app in an incognito window to rule out caching issues. Check the browser developer console for JavaScript errors that might point to the root cause.
If the issue persists after these checks, the problem likely lies in how the auth module interacts with your specific page layout and components. A developer experienced with Base44's auth internals can diagnose and resolve this quickly.

Get HelpFrequently Asked Questions
Why does my Base44 login page show a blank screen?
This usually happens when the login page is not marked as public in your auth settings, causing a redirect loop. Check your page visibility settings in the Base44 dashboard.
How do I fix the redirect loop on my Base44 login?
Go to your app's authentication settings and ensure the login page URL is added to the list of public pages that don't require authentication to access.
Can I customize the Base44 login page?
Yes, but custom styling or scripts can sometimes interfere with the auth component. Test changes incrementally and check the console for errors after each modification.
