Why ChatGPT Responses Disappear the Next Day and Must Be Regenerated: How to fix ?

Over the past several weeks, a growing number of ChatGPT users have reported a frustrating problem: responses that were visible the day before suddenly disappear and are replaced with the message “There was an error generating a response,” along with a “Regenerate” button. The issue is especially confusing because the response did successfully generate earlier and was visible at the time. Only later—sometimes hours later, sometimes the next morning—does it vanish.

This problem appears to affect the ChatGPT web interface on the OpenAI website rather than the API or other integrations. Reports suggest the issue is becoming more common and inconsistent, making it difficult for users to trust that their conversations will be preserved.

This article summarizes the symptoms, possible causes, user observations, and potential workarounds, based on multiple accounts from the community.

What Exactly Is Happening?

Users describe the same pattern:

A ChatGPT response appears normally.
The user leaves the browser or switches to another chat.
When returning later—sometimes minutes, sometimes a day later—the message is gone.
In its place is an error box saying the response failed to generate.
The “Regenerate” button appears, even though the response was successfully generated earlier.

The disappearance can occur:

After refreshing or reopening a chat
After switching to another chat
Even without leaving the page at all

Some users report that responses disappear within minutes. Others say the last several messages vanish at once, erasing part of the conversation history.

Not Just Lost Messages: “Fused Prompt” Glitches

Several users also mention another related issue: after a response disappears, any new prompt they send gets “fused” with the previous unsaved prompt. This suggests the interface is failing to store completed responses before moving on to the next request. Once the bug appears in a chat, it often continues happening repeatedly in that same conversation.

Does the Issue Affect All Devices?

Reports indicate the problem primarily affects the web version of ChatGPT, accessed through Chrome or other desktop browsers.

Users note:

The iOS app does not consistently show the missing responses either, meaning the data is not saved on the server.
Some users of the macOS ChatGPT app report the bug occurring in real time, with messages disappearing while they are still in the conversation.

This strongly suggests the issue is not device-specific and is instead tied to how the ChatGPT frontend stores or syncs conversation data.

What Users Have Tried So Far

Users have attempted typical troubleshooting steps without success, including:

Logging out and logging back in
Trying different browsers
Opening the conversation in the iOS app
Refreshing the page
Clearing browser cache

None of these reliably fix the issue.

One user noted that browser extensions such as uBlock were blocking certain analytics-related API calls on OpenAI’s site. After disabling the extension, the issue seemed to stop—although not enough evidence exists to conclude that browser blocking causes the problem for everyone. The inconsistency makes it difficult to pinpoint a universal trigger.

Is This a Known Bug?

While OpenAI has not yet issued an official public explanation, the number of consistent reports suggests that this is a real, ongoing bug in the ChatGPT frontend. The issue appears to be related to conversation syncing or saving rather than model generation itself.

The bug has been described by multiple users as:

Random
Increasing in frequency
Affecting old and new chats alike
Sometimes progressively worsening over days

Given that ChatGPT stores conversation history on its servers, the loss of messages after they appear fully generated indicates an internal failure in how the UI commits those responses to persistent storage.

Why the Issue Is Concerning

Many users rely on ChatGPT conversations for:

Work
Code generation
Research
Writing
Personal projects
Tracking decisions or evolving ideas

When the last response disappears, it can cause:

Loss of important information
Inconsistent conversation context
The need to regenerate answers that might not match the original wording
Broken continuity in longer discussions

For users, this reduces the reliability of the tool.

Are There Any Workarounds?

Until OpenAI resolves the issue, the following steps may help reduce the risk:

Copy important responses manually if they contain critical information.
Export chats regularly using the built-in export tool.
Avoid switching chats too quickly after a response is generated.
Disable aggressive ad-blockers temporarily for openai.com, in case essential API calls are unintentionally blocked.
Use the mobile or desktop apps for critical sessions, as some users report fewer issues there.
Start a new chat if one conversation becomes repeatedly unstable.

These are not guaranteed solutions, but they may minimize data loss until the underlying cause is fixed.

Conclusion

The disappearing-response issue appears to be a genuine and recurring bug affecting ChatGPT’s web interface. Users across various devices and browsers report identical symptoms: fully generated messages vanish and are replaced with error prompts, often requiring regeneration. While some temporary workarounds exist, the issue ultimately requires attention on OpenAI’s side to restore reliability and consistency.
