You click a database link in Notion and see the error message “Database Cannot Be Opened.” The page fails to load, and you cannot access your data. This error typically occurs because the database file is corrupted, the workspace is out of sync, or a third-party integration has disrupted the database structure. This article explains the root causes of this error and provides step-by-step fixes to regain access to your database.
Key Takeaways: Fixing the Notion Database Cannot Be Opened Error
- Settings & Members > Troubleshooting > Force Sync: Resolves sync corruption by forcing Notion to re-download the database from the server.
- Database Duplicate > Duplicate to Workspace: Creates a fresh copy of the broken database, often bypassing corruption in the original.
- Disconnect Third-Party Integrations: Removes integrations like Zapier or Make that may be modifying the database structure incorrectly.
Why Notion Shows “Database Cannot Be Opened”
The error “Database Cannot Be Opened” appears when Notion cannot parse the internal structure of a database page. This usually happens because the database file on the local device or server has become corrupted. Corruption can occur after a sudden power loss, a failed sync, or a buggy update from a third-party integration.
Another common cause is a broken relation between two databases. If a linked database references a parent database that has been deleted or renamed, Notion may refuse to open the child database. Similarly, a formula column that references a missing property can cause the entire database to fail to load.
Finally, the error can occur when the database exceeds Notion’s internal size limits. While Notion doesn’t publish a strict row limit, databases with tens of thousands of rows or many large file attachments can become unstable. The “Database Cannot Be Opened” error is Notion’s way of protecting the application from crashing.
Steps to Fix a Database That Cannot Be Opened
Follow these steps in order. Each step attempts a different recovery method. Test the database after each step before moving to the next.
- Force a manual sync of the workspace
Open Notion and go to Settings & Members from the left sidebar. Select Troubleshooting from the menu. Click Force Sync. Wait for the sync to complete. This re-downloads the database from the server, overwriting any corrupted local cache. - Duplicate the database
If force sync doesn’t work, duplicate the database. Right-click the database page in the sidebar and select Duplicate. Then choose Duplicate to Workspace. Rename the duplicate and try opening it. The duplicate often bypasses corruption in the original file. - Remove broken relations and formula columns
If you can access the database but it fails to load fully, create a new view. Click the + Add a View button at the top of the database. Choose a Table view. If the new view loads, switch to the original view and delete any relation columns that link to deleted databases. Also remove any formula columns that reference missing properties. - Export and re-import the database
If the database is still unopenable, export it. Go to Settings & Members > Settings > Export. Select Markdown & CSV format. Uncheck Include content to export only the database structure. Then create a new database in Notion and import the CSV file. This rebuilds the database from scratch. - Disable third-party integrations
Go to Settings & Members > Connections. Review all connected apps. Disconnect any integration that has write access to the database, such as Zapier, Make, or a custom API tool. After disconnecting, try opening the database again. - Clear the Notion cache (desktop app only)
Close Notion completely. Press Windows Key + R, type %appdata%\Notion, and press Enter. Delete the Cache folder. Restart Notion. This removes corrupted cached data that may be causing the error.
If Notion Still Has Issues After the Main Fix
Database opens but shows no content
If the database page opens but displays a blank screen, the view may be filtered incorrectly. Click the Filter button at the top of the database and remove all active filters. If that doesn’t work, create a new view as described in step 3 above.
Error appears on mobile but not on desktop
This usually indicates a sync issue on the mobile device. Force close the Notion app, reopen it, and pull down on the database list to trigger a manual refresh. If the error persists, uninstall and reinstall the Notion mobile app.
Database cannot be opened after renaming
Renaming a database that is referenced by other databases can break relations. If you renamed the database, revert to the original name. Then update all linked databases to point to the correct database name. Use the Duplicate method (step 2) to create a new copy with the desired name.
Notion Free vs Plus vs Business: Limits That Affect Database Stability
| Item | Free | Plus | Business |
|---|---|---|---|
| File upload limit | 5 MB per file | Unlimited | Unlimited |
| Version history | 7 days | 30 days | 90 days |
| Guest access | Limited to 10 guests | Unlimited guests | Unlimited guests with permissions |
| Database row limits | No strict limit but performance degrades above 10,000 rows | No strict limit but performance degrades above 10,000 rows | No strict limit but performance degrades above 10,000 rows |
| Third-party integrations | Limited to 5 | Unlimited | Unlimited with admin controls |
The table above shows that database row limits are not explicitly tiered, but large databases on any plan can become unstable. If your database exceeds 10,000 rows, consider archiving old data into a separate database to prevent the “Database Cannot Be Opened” error.
You can now recover a broken Notion database using force sync, duplication, or export and re-import. If the error recurs, review your third-party integrations and database size. As an advanced tip, use the Linked Database feature to split a large database into smaller, related databases that are easier to maintain.
