Lovable app not working? How to fix it and get unstuck
Last reviewed 3 November 2026
It worked yesterday, and now it’s broken. Every new prompt seems to fix one thing and break another, and your credits are going fast. Stop prompting for a moment and work through this instead.
First check Lovable’s status page, then go back to the last version that worked using version history. Describe what you see and what you expected, investigate before changing anything, and make one small change at a time. If the same problem keeps returning, especially around data, sign-in or payments, get a developer to look.
Before you send another prompt
- Check whether it’s Lovable or your app. Look at Lovable’s status page. If there’s an incident, wait for it to clear.
- Protect your code. Connect the project to GitHub or download your codebase, so you always have your own copy.
- Protect your data. If real customers use the app, read Lovable’s database backup guide and export a copy before you change anything. Reverting your code and restoring your data are separate things.
- Note what changed. Find the last prompt before it broke. That’s your best clue.
Get out of the fix loop
Repeating “fix it” tends to pile changes on top of a wrong guess. Lovable’s own troubleshooting advice also says not to keep retrying the same prompt. Try this order:
- Ask it to investigate, not fix. Say what you did, what you expected and what happened. For example: “The login form does nothing on mobile. Walk me through what’s happening.”
- Go back to a working version. Lovable saves every change, so you can revert from version history, then retry with a clearer prompt.
- Use Plan mode for anything bigger. Plan mode looks into the problem without touching your code, so you can read the plan before you build.
- Make one change at a time, and test it before you ask for the next one.
- Read the logs. Lovable has built-in logs for functions, the database and sign-in. Paste the exact error into your prompt.
What common problems usually mean
| What you see | Usually points to | Try first |
|---|---|---|
| Blank or white page | A code error while the page loads, or a recent change that broke it | Revert to the last working version, then look at the browser console errors |
| Works in preview, not when published | Settings, secret keys or sign-in addresses that differ on the live site | Check the published address is allowed in your sign-in settings, and republish |
| Build unsuccessful | The latest change has a code error, which also blocks publishing | Use Try to fix once, then revert if it comes back |
| Sign-in or email verification fails | Email or redirect settings, often after moving to your own domain | Check the auth logs and your email and redirect settings |
| Data missing or “permission denied” | Database access rules | Be careful here. Don’t open the rules up just to make the error go away |
| Exceeded quota | A limit on your plan, or on a service your app uses, such as an AI provider | Read the error to see which service it names, then check that account’s usage |
| Stuck on thinking or chat frozen | A temporary problem or an overloaded request | Check the status page, reload, and split the request into smaller steps |
| GitHub sync not working | The connection needs authorising again, or you’re on a different branch | A workspace or project admin can reconnect it, and check which branch is syncing |
These are common patterns, not a diagnosis, and Lovable changes quickly. Check its documentation for the current steps.
One warning: don’t weaken security to fix an error
When data won’t load, an AI tool may suggest loosening your database rules. The error goes away, and sometimes so does the protection for your customers’ data. Run Lovable’s security scans after any change like this, then work through our security checklist.
When to stop prompting and get help
- The same problem has come back after several attempts.
- Each fix breaks something that worked before.
- Real customers, payments or personal data are involved.
- You’re spending more credits on repairs than on new features.
- You can no longer explain what the app’s code is doing.
None of that means you did anything wrong, or that you have to start again. You now have a working prototype that shows exactly what you want, which is a great starting point. See how we make AI-built apps ready for real customers.
Questions founders ask
Will I lose my work if I revert?
Lovable says nothing gets lost when you revert, as it keeps your version history. Database content is separate, so read its backup guidance if real data is involved.
Can a developer work on a Lovable project?
Yes. Lovable’s GitHub sync lets developers work on the code in their own tools, and their changes on the active branch sync back into Lovable.
Should I rebuild it somewhere else?
Not as a first step. Moving a broken app to another tool usually moves the problems as well. Find out what’s wrong first, then decide. We start with a written audit for this reason.
