Seeing the WordPress white screen after migration can be frustrating, especially when you expect your site to work perfectly after moving it to a new server or domain. Instead of your homepage or content, all you get is a blank, white page with no error message to guide you. This issue, often called the “White Screen of Death,” is common but completely fixable.
In this guide, we will walk through the main reasons why you might face the WordPress white screen after migration and show you step-by-step solutions to get your site running again. Whether the cause is theme conflicts, plugin errors, memory limits, or incomplete file transfers, you will learn exactly how to identify and resolve the problem quickly.
First, Why Does the WordPress White Screen Shows Up?
The WordPress white screen typically appears when a critical error occurs behind the scenes. Instead of showing an error message, WordPress just gives up and displays a blank page.
Here are some of the most likely causes:
- There may be PHP errors or a version mismatch following the migration.
- Incomplete or corrupted theme or plugin files
- Memory exhaustion on your server
- There may be issues with your .htaccess file or the permissions of your files.
- Incorrect database connection settings
Each of these can cause your WordPress white screen to come up, especially after a migration when paths, URLs, and configurations shift.
Let’s fix it.
What are the steps to diagnose and fix the WordPress white screen issue?
Just like any problem in WordPress, we solve it by narrowing down the source. Here are the exact steps you can follow.
Enable Debugging
Start by turning on debugging in your wp-config.php file.
Add this:
define('WP_DEBUG', true);
define('WP_DEBUG_LOG', true);
define('WP_DEBUG_DISPLAY', false);This will log any errors to a file called debug.log inside your /wp-content/ folder. If a plugin or theme is breaking your site, you’ll see clues here.
Check Theme and Plugin Compatibility
Sometimes, a plugin that worked fine on the old server isn’t compatible with the new PHP version. Or maybe your theme didn’t transfer properly.
What to do:
- Rename your /plugins/ folder via FTP to disable all plugins.
- If the white screen disappears, you’ve found the issue.
- Reactivate plugins one by one to find the troublemaker.
- Do the same with your /themes/ folder.

Increase the PHP memory limit.
Your new host might have lower default memory limits than your old one.
To fix it:
- Open wp-config.php
- Add this line above the “That’s all, stop editing!” comment:
define('WP_MEMORY_LIMIT', '256M');This often resolves the WordPress white screen issue caused by memory exhaustion.
Check File Permissions and Ownership
If your file permissions are too restrictive, WordPress might not be able to load essential scripts.
Recommended permissions:
- Folders: 755
- Files: 644
You can update these via FTP or your hosting control panel.
Replace .htaccess and Check URLs
A corrupted .htaccess file can break your site. Try renaming it to .htaccess_old and reload the site.
Also, ensure your site URL and home URL match the new domain:
define('WP_HOME', 'https://yournewsite.com');
define('WP_SITEURL', 'https://yournewsite.com');Add these to wp-config.php temporarily to override incorrect values.
A Quick Recap: Fixing That WordPress White Screen Fast
- Turn on debugging to catch silent errors.
- Deactivate themes and plugins.
- Raise your memory limit.
- Fix file permissions and corrupt .htaccess.
- Double-check URL settings after migration.

FAQs
Why does my WordPress White Screen appear with no error?
This usually happens because WordPress suppresses critical errors. Turning on debug mode will help reveal the issue.
Can a plugin cause a WordPress white screen after migration?
Absolutely. If a plugin is incompatible with the server or corrupt during transfer, it can break the site.
Is the WordPress white screen dangerous for my site?
Not inherently, but it blocks access for users and admins. It’s critical to resolve it quickly to restore functionality.
What if I can’t access wp-admin?
Disable plugins or themes via FTP. You can also reset your theme in the database using phpMyAdmin if needed.
Will restoring from backup help?
Yes, if the backup is clean and matches the new server’s requirements. But make sure to adjust URLs and settings post-restore.
