WordPress displays it when the db_version value stored in your site matches the database version required by the installed WordPress core files. In that state, there is no core database migration left to run.

The message becomes a problem only when it appears repeatedly, prevents access to the dashboard, or sends you back to the same screen after every login. That pattern usually indicates stale cache or another request-state problem rather than a damaged database.

WordPress core keeps a database-version number in the db_version option. The installed core files contain the version of the database schema they expect. When you open /wp-admin/upgrade.php, WordPress compares those two values.
- If the values match, WordPress shows the heading No Update Required and the sentence “Your WordPress database is already up to date!”.
- If the stored value is lower than the version required by the files, WordPress shows Database Update Required and asks you to continue with the database upgrade.
A core-file update and a database update are related but separate operations. Replacing WordPress files does not necessarily mean that a schema migration must run. Conversely, after files are updated, WordPress may need to execute one or more database upgrade routines before the site is fully aligned.
#1 Best Overall
The wording is intentionally a status result. WordPress changed the older “up-to-date” spelling to “up to date”; the current interface uses the latter wording.
When seeing the message is normal
After a core update
It is normal to visit the upgrade endpoint once after updating WordPress and land on the no-update screen. The database may already have the required schema because the update was completed earlier, an automatic update finished the migration, or no schema change was needed for the particular version transition.
When you open the endpoint directly
An administrator can also reach /wp-admin/upgrade.php manually while the installation is current. WordPress performs the same comparison and reports that there is nothing to do. Select Continue to return to the site or administration area.
What the message does not mean
It does not mean that every plugin, theme, custom table, or application connected to the site is current. The check concerns WordPress core’s own database version. Plugin migrations are tracked separately and can appear even when this core message says no update is required.
Why the screen can become a login loop
A one-time completion page is harmless. A page that appears on every login, replaces dashboard links, or returns immediately after selecting Continue indicates that the result is not being delivered or stored consistently between requests.
Browser cache
Your browser may retain an old upgrade response or redirect. Test the login in a private window first. If the private window works, clear the normal browser’s cached data and cookies for the site, then sign in again.
Do these 3 things before closing this tab:

A hosting control panel, page-cache plugin, reverse proxy, or content-delivery network can serve an old admin response. Purge the page cache at each layer your site uses. There is no universal button name: look for controls labelled Purge, Clear cache, Flush cache, or Invalidate in the relevant host or cache service.
Persistent object cache
Redis- or Memcached-backed object caching can remain active through multiple requests. A persistent object-cache drop-in can preserve stale options even after a page cache is purged. If WP-CLI is available, run wp cache flush from the WordPress installation directory. This clears the object cache; it does not automatically purge a separate CDN or browser cache.
Plugin or theme interference
A plugin or theme can alter authentication, redirects, caching, or the upgrade request. Treat this as a diagnostic possibility, not a universal cause. If clearing the cache layers does not stop the loop, back up the site or work on staging, then deactivate the suspected plugin. If necessary, switch temporarily to a default WordPress theme and test again. Restore components one at a time after identifying the conflict.

Use this order so that you do not change production code before checking the simplest causes:
The Tool Desk
Outbyte Driver Updater FREEScan for outdated or missing drivers - takes under a minuteDriver Scan →Outbyte PC Repair FREERepair Windows errors before they cause bigger problemsFix Now →- Open the site in a private browser window and try the normal login URL.
- Clear the browser cache and site cookies if the private window succeeds.
- Purge page caches from the host, cache plugin, reverse proxy, and CDN layers that your site actually uses.
- Flush persistent object cache, if enabled. With WP-CLI, use
wp cache flushfrom the site’s WordPress directory. - Open
/wp-admin/upgrade.phponce more and select Continue. - If the loop remains, create a current database backup and use staging where possible before disabling plugins or changing themes.
Do not delete tables or alter version values merely to dismiss the screen. Those actions can hide the symptom while leaving an incomplete migration or creating a harder-to-diagnose state.
Checking the database from the command line
WP-CLI provides an official comparison command for sites where you have shell access. Run it from the WordPress installation directory:
Rank #4
wp core check-update-dbThe command compares the current database version with the version required by the installed WordPress core. When no migration is needed, it can return:
Success: WordPress database is up to date.For a multisite network, add the network flag:
wp core check-update-db --networkThese commands inspect status; they do not replace the need to protect the site before making changes.
Running the official database procedure
If the check reports that the database is behind, use WordPress’s database-update command:
wp core update-dbOn a multisite network, use:
wp core update-db --networkYou can compare what would be done without changing data by adding --dry-run:
wp core update-db --dry-runUse a dry run when you need to confirm the detected state before scheduling the migration. A production update should still have a tested backup, a maintenance window, and a rollback plan. After the procedure completes, flush object, page, and browser caches as appropriate, then retry the dashboard.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.A safe repair sequence for shell-access sites
- Back up first. Take a database backup and verify that it can be restored. Keep a copy of the current files if the core update itself was recent.
- Confirm the target. Change to the correct WordPress path and, for multisite, confirm that you are operating on the network installation rather than a separate site.
- Inspect status. Run
wp core check-update-db, adding--networkfor multisite. - Preview if needed. Run
wp core update-db --dry-runwhen you want a non-writing comparison before execution. - Run only when required. Execute
wp core update-db(or the network form) if the check identifies pending core migrations. - Clear stale state. Run
wp cache flushwhen a persistent object cache is in use, then purge other cache layers separately. - Retest access. Sign in through a fresh browser session and confirm that normal dashboard links work.
Never “repair” the issue by manually editing the db_version option. WordPress’s documented commands perform the comparison and migration logic; changing the number alone can mark an incomplete database as finished.

Core database updates versus plugin migrations
The no-update message is limited to WordPress core. A plugin can maintain its own schema version and request a migration independently. For example, a commerce plugin may display an “update database” notice while WordPress core reports that its database is current. The two states are not contradictory because they refer to different migration systems. A support case documenting this distinction is available at WordPress.org support.
When a plugin requests an update, follow that plugin’s documented procedure, requirements, and backup guidance. Do not assume that rerunning wp core update-db will migrate plugin tables.
Normal completion or a real loop?
| Sign | Likely interpretation | Next action |
|---|---|---|
| The screen appears once after an update | Core and database versions already match | Select Continue and carry on |
You opened /wp-admin/upgrade.php directly |
The installation is already current | Return to the dashboard |
| The screen appears on every login | Stale browser, page, CDN, or object-cache state is likely | Purge each cache layer and retry |
| The dashboard remains blocked after cache purges | A plugin, theme, redirect, or access conflict may be involved | Back up, test on staging, and isolate components |
| WP-CLI reports a pending update | The database is behind the installed core files | Run the official update procedure during a maintenance window |
| A plugin asks for its own database update | A separate plugin migration is pending | Use the plugin’s migration process, not the core command |
Common mistakes to avoid
- Running the core update repeatedly: If the check already says the database is current, repeated runs do not solve a cache loop.
- Purging only one cache: A browser purge cannot clear a CDN response, and a CDN purge cannot clear a persistent object cache.
- Disabling plugins without a backup: Use staging when possible and record which components you deactivate.
- Editing
db_versionby hand: The number is a status marker, not a substitute for migration routines. - Confusing plugin and core notices: Identify which component owns the update request before choosing a command.
When to escalate
Contact your host or a WordPress professional when the loop survives browser, page, CDN, and object-cache purges; when WP-CLI cannot complete the procedure; or when logs show database errors, permission failures, or interrupted migrations. Provide the WordPress version, whether the site is multisite, the exact URL being redirected to, the cache layers in use, and the output of wp core check-update-db. Do not post passwords, database credentials, salts, or full configuration files in a support request.
