My App Loads but Shows a Blank White Screen
You open your app or website and instead of seeing your content, you get nothing. Just a plain white screen. The page seems to load (the tab title might even show your app name), but the screen stays completely empty.
This is sometimes called the "white screen of death" and it's one of the most common problems with web apps. The frustrating part is that there's no obvious error message — just nothing. Your users see the same blank page and probably think your site is broken or doesn't exist.
The good news is that this usually has a specific, fixable cause. The bad news is that figuring out which one requires looking at things most non-technical people don't know how to check.
Error Messages You Might See
Blank/empty page
Uncaught TypeError
Failed to fetch
ChunkLoadError
net::ERR_BLOCKED_BY_CLIENT
Common Causes
- JavaScript error blocking the page — Your app needs JavaScript to display content, and a single error can stop everything from showing up
- Missing environment variables — Your app is looking for configuration values (like database addresses) that don't exist in production
- Wrong build settings — The app was built with incorrect settings so the files it needs can't be found
- API or database is down — Your app tries to load data before showing anything, and the data source isn't responding
- Blank index.html — The main page file is empty or was overwritten during deployment
- Browser blocking resources — Ad blockers, security extensions, or corporate firewalls are blocking files your app needs
How to Fix It
- Open the browser console — Press F12 (or right-click and choose "Inspect"), then click the "Console" tab to see error messages in red
- Try an incognito/private window — This rules out browser extensions and cached files as the cause
- Check if your backend is running — If your app loads data from a server, make sure that server is online and responding
- Look at the page source — Right-click the white page and choose "View Page Source" to see if there's any content at all
- Check deployment logs — Go to your hosting platform and look for error messages from the most recent deployment

Get HelpFrequently Asked Questions
Why is there no error message on the screen?
Modern web apps use JavaScript to build the entire page. If JavaScript fails, there's nothing to show the error to you on the page itself. The errors are hidden in the browser's developer console (press F12 to open it).
It works on my phone but not my computer (or vice versa). Why?
Different browsers and devices handle things differently. It could be a browser extension blocking something, an outdated browser that doesn't support your app's code, or a cached version on one device.
