Quick Answer

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.

Step-by-Step Fix

  1. Confirm the exact symptom

    • Write down the exact error, failed action, and when it started.
    • Check whether the issue happens on one account, one workspace, or every environment.

  2. Check account, billing, and permissions

    • Verify you are signed into the correct account or team workspace.
    • Confirm your plan, credits, or permissions still include the feature you need.

  3. Rule out browser/app state problems

    • Sign out and sign back in.
    • Clear cache/cookies for the service.
    • Disable extensions temporarily and test in a private window.

  4. Check official product signals

    • Review the help center, billing page, admin settings, or status page.
    • Look for incidents, plan restrictions, or policy limitations.

  5. Collect proof and escalate if needed

    • Save screenshots, timestamps, request IDs, and repro steps.
    • Include app/browser version and your network environment.

Common Root Causes

  • Wrong account or workspace
  • Expired or mismatched subscription/plan
  • Missing permissions or role access
  • Browser cache, cookies, or extension conflicts
  • Temporary incidents, limits, or policy restrictions

Prevention Tips

  • Keep one clean browser profile for important workflows
  • Document billing owner and admin access in your team
  • Review plan limits before large usage spikes or uploads
  • Save official status/help links for faster troubleshooting

Claude Attachments Not Uploading or Failing to Process? Here's the Fix

Claude Pro supports file uploads up to 10 MB per file; supported formats include PDF, Word (.docx), plain text, images (PNG/JPG/GIF/WebP), and most code files. If your attachment fails or won't process, the most common causes are an oversized file, an unsupported format, a stale browser session, or a network/extension block. Clear site data for claude.ai, disable ad blockers, and retry in incognito — that resolves the issue in the majority of cases.

Claude Blank Page / White Screen: Fix Cache, Extensions, and Script Blocking

A Claude blank page or white screen is almost always caused by a stale browser cache, a script-blocking extension, or a VPN blocking WebSocket connections. Open an incognito window and sign in — if Claude loads there, clear all site data for claude.ai in your main browser and disable extensions one at a time. If Claude is blank in incognito too, disable your VPN and check status.anthropic.com for active outages.

Claude error loading chat – How to Fix

Claude's 'error loading chat' message appears when a conversation fails to sync from the server or a browser extension blocks the loading request. Refresh the page once, then try opening the conversation in an incognito window. If a specific chat refuses to load on all devices, that conversation's data may be corrupted on Anthropic's servers — start a new conversation to continue your work.

How to report a Claude bug effectively (what to include)?

Report Claude bugs at support.anthropic.com. An effective bug report includes: the exact error message, the specific steps that reproduce it (not just 'it stopped working'), your browser and OS version, whether it happens in incognito, and whether it affects all conversations or just one. Including a screenshot and the approximate timestamp speeds up resolution significantly.

How to fix Claude error while generating (stops mid-response)?

Claude stopping mid-response is usually caused by a network interruption, a browser extension blocking the streaming connection, or the response hitting a length or usage limit. The fastest fix is to refresh the page, disable extensions, and retry with a more focused request. If Claude consistently stops at the same point in a response, the content itself may be triggering a safety check — try rephrasing the request.

Claude Something Went Wrong: Causes and Fixes

If the error persists, clear your browser cookies for claude.ai and try a private window. This error almost never indicates an account problem — it is usually a temporary connection or session issue.
