Quick answer: If WordPress shows a white page after an update with no visible error, start by disabling the last updated plugin, switching to a default theme, and checking Recovery Mode or server error logs. This is usually caused by a plugin conflict, theme incompatibility, PHP fatal error, or incomplete update files. Do not restore, reinstall, or overwrite WordPress files until these safer checks are complete.

Most users apply the wrong fix. Use the correct path first.
Quick Fix Checklist
- Deactivate the plugin or theme that was updated right before the white page appeared.
- Switch the site to a default WordPress theme such as Twenty Twenty-Four.
- Check whether WordPress Recovery Mode email was sent and use the recovery link if available.
- Clear any application-level cache from your host or caching plugin.
- Confirm the updated plugin, theme, and WordPress core all support your current PHP version.
What To Do After Each Fix
- If disabling the last plugin fixes the white page: keep that plugin disabled, check compatibility notes, and test it on staging before reactivating.
- If switching themes fixes it: the active theme or child theme likely has a PHP or template conflict after the update.
- If Recovery Mode identifies a file: repair that specific plugin or theme instead of restoring the whole site.
- If logs show a PHP fatal error: fix the named function, memory limit, or PHP version before reinstalling WordPress core.
Causes
A white page with no error after an update usually means WordPress hit a fatal conflict but is not displaying the message. The issue is often tied to the most recent change, especially if the site worked before the update.
| Cause | What it means | Fix |
|---|---|---|
| Plugin conflict after update | An updated plugin breaks page rendering or triggers a fatal error. | Deactivate the last updated plugin and test the site. |
| Theme conflict after update | The active theme is no longer compatible with the current WordPress version. | Switch to a default theme and retest. |
| PHP compatibility issue | The update requires a PHP feature your site does not support. | Use a compatible PHP version or update the affected extension. |
| Corrupted update files | Files were replaced incompletely during the update process. | Reinstall the affected plugin, theme, or WordPress core files. |
| Hidden fatal error | Error display is off, so WordPress shows only a blank page. | Use recovery mode or enable debugging temporarily to identify the failing component. |
Step-by-Step Fix
- Check what changed last. Identify the plugin, theme, or WordPress core update that happened right before the white page appeared.
- Use Recovery Mode if WordPress sent it. Open the recovery link from the admin email and sign in to isolate the failing plugin or theme.
- Deactivate the last updated plugin. If you cannot access wp-admin, disable it from your hosting file manager or by renaming its folder in
wp-content/plugins. - Switch to a default theme. Rename the active theme folder or activate a default theme to see whether the blank page disappears.
- Reinstall the affected component. Replace a corrupted plugin, theme, or WordPress core file set with a clean copy from a trusted source.
- Check PHP compatibility. Confirm the updated component supports your server’s PHP version and adjust only if the plugin or theme requires it.
- Clear application cache. Purge cache from your caching plugin, host dashboard, or CDN so the site does not keep serving the broken page.
- Reactivate items one at a time. Once the site loads, turn plugins back on individually to find the exact conflict before restoring normal use.
Still Not Working
- Restore the site from the last backup taken before the update.
- Re-upload fresh copies of WordPress core files, keeping
wp-contentintact. - Temporarily disable all plugins, then re-enable them one by one to isolate the failure.
- Check the server error log from your hosting control panel for the exact file or component causing the blank page.
- Contact the plugin or theme developer with the update version, PHP version, and the exact time the white page started.
Frequently Asked Questions
Why does WordPress show a white page with no error after update?
It usually means a fatal conflict happened during the update, but error output is hidden, so the page appears blank.
How do I find the update that caused the white page?
Start with the plugin, theme, or core update that was installed most recently before the site went blank.
Can a theme update cause a white page in WordPress?
Yes. A theme update can break compatibility with your WordPress version or PHP version and stop the page from loading.
Will Recovery Mode fix the white page automatically?
No, but it can let you log in and disable the broken plugin or theme that caused the issue.
Should I reinstall WordPress core if the site is blank after an update?
Yes, if the blank page started after a core update or if core files may have been corrupted during the update.
