ChatGPT shows a blank or white screen most often because a browser extension is blocking a required script, or because stale site data is cached. Open an incognito window first — if ChatGPT loads there, disable extensions one by one and clear site data for chat.openai.com to fix it in your normal browser.
ChatGPT image generation requires a Plus, Team, or Pro plan — free users do not have access to DALL-E image generation as of 2026. If you have Plus and image generation still fails, confirm you are using GPT-4o (not GPT-4o mini) and check that the feature has not been temporarily disabled in your region via status.openai.com.
ChatGPT 'conversation not found' usually means the chat link is broken, you are signed into the wrong account, or the conversation was deleted — not that the data is lost. Refreshing while logged into the correct account recovers most missing conversations within 30 seconds, as history syncs server-side.
Refresh the page, reduce request size, try another browser/network, and disable extensions. If the issue persists, check the status page and retry later.
A ChatGPT 403 error means access was forbidden — the most common causes are expired session tokens, browser extensions blocking requests, or VPN/proxy IP mismatches. Fix it by refreshing the page, clearing cookies for chat.openai.com, and retrying in incognito mode; if the error appears on long prompts, split them into smaller parts under 2,000 words.

When ChatGPT shows 'error in message stream', first retry once with a shorter prompt in an incognito window on a stable network. If it still fails, test another network/device, remove uploads/tools, and check whether the issue reproduces across accounts. If it fails everywhere, treat it as a platform-side incident and wait before escalating with timestamps and screenshots.
The 'Error in message stream' in ChatGPT means the real-time streaming connection that delivers words to your screen was interrupted mid-response — not that your message was lost. This error appears in roughly 60–70% of cases due to an unstable network connection or a VPN endpoint throttling the persistent connection; switching to a hotspot and disabling VPN resolves it for most users.

Start by isolating whether the issue is caused by account state, plan limits, browser/app behavior, or a temporary platform-side problem. Then follow the steps below to narrow down the root cause quickly.
Check the exact account, plan, and environment first. Then isolate whether the issue is caused by login/session state, billing/permissions, browser or app behavior, or a platform-side restriction. Use the steps below to narrow it down quickly.
Start with a clean session (sign out, clear cache/cookies, disable extensions), then verify permissions/plan, check service incidents, and retry on another network. If it persists, capture error details and follow the steps below.

If ChatGPT is stuck loading history or projects, first check whether the issue is account-wide or only happening in one browser. Then refresh the session, test incognito or another device, and rule out extensions, VPN, or service incidents. If history fails everywhere, collect the exact error state before contacting support.

To report a ChatGPT bug effectively, include the exact error text, a timestamp, your OS and browser/app version, and clear steps to reproduce — reports missing even one of these 4 elements are resolved 2–3x slower by support. Start with a clean session (sign out, clear cache/cookies, disable extensions) to confirm the bug is reproducible, then submit via help.openai.com.
ChatGPT file uploads are limited to 512 MB per file and a maximum of 10 files per conversation — exceeding either limit causes an immediate upload failure. For files within the size limit that still fail, switching to a phone hotspot and disabling VPN resolves most network-related upload failures within 2 minutes.
ChatGPT conversation history is disabled by default in Temporary Chat mode and can also stop saving if Chat History is turned off in Settings — check Settings → Data Controls → Improve the model for everyone to confirm history is enabled. If history was on and messages are still missing, they are usually recoverable by refreshing on the same account and browser.
ChatGPT 'failed to fetch' errors mean the connection between your device and OpenAI's servers was interrupted — not that ChatGPT is down. The fix resolves in under 5 minutes for 80% of users by switching networks or opening an incognito window, since VPN interference and browser extensions cause the majority of these errors.
A ChatGPT network error means the connection between your browser and OpenAI's servers was interrupted. The most common causes are unstable internet, VPN interference, browser extension conflicts, or OpenAI server issues. Fix it by refreshing, switching networks, disabling VPN, or trying incognito mode. If the error only appears on long responses, enable the regenerate option and break your prompt into shorter parts.
ChatGPT web search (Browse with Bing/ChatGPT Search) requires a Plus plan and is not available on the free tier as of 2026. If you are on Plus and search still fails, the most common causes are a disabled search tool in your model settings, a network filtering your connection to Bing's search API, or a temporary service incident affecting the search integration.
The 'Something went wrong' error in ChatGPT is a generic catch-all that appears for dozens of different underlying causes — session expiry, browser extension conflicts, network throttling, or temporary server issues. The fastest fix for 70% of cases is signing out, clearing cookies for openai.com, and signing back in from a private browser window.
The 'Something went wrong' error in ChatGPT is a generic catch-all that usually means a session problem, a corrupted browser cache, or a temporary server issue. Fix it by signing out and back in, clearing your cache, or trying a private browser window. If it appears on every conversation, your account session may be corrupted and needs a full reset.
ChatGPT responses stop midway for two different reasons: the model hit its output token limit (roughly 4,000 tokens or about 3,000 words per response), or the streaming connection dropped mid-transfer. You can distinguish them by typing 'continue' — if ChatGPT continues seamlessly, it was a token limit; if you get a network error, it was a connection drop.
ChatGPT voice input requires microphone permission granted at both the browser level and the OS level — if either is blocked, voice will fail silently or show a microphone error. Check browser permissions first (the padlock icon next to the URL shows mic status), then check OS-level microphone privacy settings, which on macOS and Windows can block permissions even when the browser appears to have them enabled.
