ChatGPT Not Loading / Blank Screen — How to Fix It

If ChatGPT opens to a blank white or dark screen with no chat interface visible, you are not alone. This issue typically affects users whose browsers have stale cached files, conflicting extensions, or corrupted cookies from a previous session. Following the steps below will resolve the problem in most cases without needing to reinstall anything.

Why does this error happen?

ChatGPT's web app is a React-based single-page application that relies on JavaScript bundles, service workers, and session cookies loading correctly in sequence. When the browser serves an outdated cached version of these assets, or a third-party extension such as an ad blocker or privacy tool intercepts a critical network request, the app's JavaScript can fail silently, leaving the DOM in a partially rendered or entirely empty state. Corrupted or expired authentication cookies can also prevent the app shell from initializing, resulting in the same blank-screen symptom across both light and dark browser themes.

How to fix it

Clear Browser Cache and Cookies

Open your browser settings and navigate to the option to clear browsing data. Select 'Cached images and files' and 'Cookies and other site data', set the time range to 'All time', then confirm. After clearing, reload chat.openai.com and check whether the interface appears.

Disable All Browser Extensions

Go to your browser's extensions or add-ons manager and toggle off every installed extension, paying particular attention to ad blockers, VPNs, and script managers. Reload ChatGPT with extensions disabled to confirm one of them is the culprit. Re-enable extensions one at a time to identify which specific extension causes the blank screen.

Try Incognito or Private Browsing Mode

Open a new incognito or private window using Ctrl+Shift+N (Chrome/Edge) or Ctrl+Shift+P (Firefox), then navigate to chat.openai.com. Incognito mode starts without cached data or active extensions, making it a fast way to confirm whether the issue is environment-specific. If ChatGPT loads normally in private mode, the problem lies in your standard browser profile.

Try a Different Browser

Install or open an alternative browser — for example, switch from Chrome to Firefox or Microsoft Edge — and attempt to load ChatGPT. If the interface loads correctly in another browser, your primary browser's profile, settings, or a deeper cache corruption is the root cause. You can then reset your primary browser profile or reinstall it to resolve the issue permanently.

Pro tip

Add chat.openai.com to your browser's trusted sites list and whitelist it in any ad blocker or firewall settings proactively. This prevents extensions from accidentally blocking the JavaScript bundles that ChatGPT needs to render its interface after future updates.

Frequently asked questions

Why does ChatGPT show a blank screen only on my work computer?

Corporate networks often route traffic through firewalls or proxy servers that can block the JavaScript assets ChatGPT requires to load. Ask your IT department to whitelist chat.openai.com, or try accessing it via a mobile hotspot to confirm network-level blocking.

I cleared my cache and disabled extensions but ChatGPT still shows a blank screen — what next?

Check the OpenAI status page at status.openai.com to see if there is an active incident affecting the web app. If no incident is reported, try resetting your browser profile entirely or reinstalling the browser, as deep profile corruption can persist even after a standard cache clear.

Does this blank screen issue happen on the ChatGPT mobile app too?

The mobile app uses a different rendering path, but similar symptoms can occur if the app's local cache is corrupted. Force-close the app, clear its cache from your device's app settings, and relaunch it to resolve the issue on iOS or Android.
