Common WordPress Issues After Migration or Domain Change
When you migrate your WordPress site to a new host or change your domain, you may find that your WordPress site might not be working after migration. This is often due to the following problems may occur:
- Broken Links and Missing Images
- Incorrect Permalinks
- WordPress Site Not Loading
- Database Connection Errors
- SSL Certificate Errors
- Theme and Plugin Issues
- Redirection Problems
- Email Issues
1. Broken Links and Missing Images
One of the most common issues people face after migrating a WordPress site to a new domain or server is broken links or missing images. You might notice that some pages don’t load correctly, images are missing, or clicking certain links takes you to an error page. This can be frustrating — and confusing — especially when everything looked fine before the move.
The reason this often happens is because your WordPress database still contains URLs (web addresses) from the old domain. Even though the site has been moved to a new location, those old links are still pointing back to the original domain or file path. For example, an image that used to load from oldsite.com/wp-content/uploads is still trying to pull from that location, even though the site now lives at newsite.com.
To fix this follow these steps:
Use a Search and Replace Tool
After a migration, the easiest way to fix broken links or missing images is by using a Search and Replace tool like Better Search Replace or Search Replace DB. This tool allows you to search your database for the old URL and replace it with the new one.
Update Image URLs
If images aren’t showing up after migration, make sure the URLs in the database reflect the new domain. You can also use the Regenerate Thumbnails plugin to make sure all your images display correctly.
2. Incorrect Permalinks
Another common issue after migrating a WordPress site is permalink problems, which can result in 404 errors — meaning your pages or posts can’t be found when someone tries to visit them. This can be especially frustrating if your content is still there, but WordPress simply doesn’t know where to find it.
This usually happens when the URL structure (permalinks) changes during the migration process. For example, your old site might have used URLs like yoursite.com/blog/post-title, but after migration, WordPress might default to something like yoursite.com/?p=123. If visitors or search engines try to access the original links, they’ll land on error pages.
Sometimes, even if the URL structure hasn't changed, WordPress may temporarily “forget” the correct settings due to server configuration changes or missing .htaccess rules — especially if you moved to a new hosting environment.
Reset Permalinks
Go to Settings > Permalinks in your WordPress dashboard. Without making any changes, click Save Changes. This will flush the rewrite rules and regenerate the correct permalink structure.
Check .htaccess File
If the issue persists, check your .htaccess file for errors. You can regenerate the file by simply saving the permalinks as mentioned above, or you may need to manually edit the file if you're using custom rules.
3. WordPress Site Not Loading After Migration
If your WordPress site isn’t loading after a migration or domain change, don’t panic — this is a common issue, and it’s usually caused by one of a few technical hiccups that can be fixed with the right steps.
Check Database Credentials
The most common reason is incorrect database settings. During a migration, your website's files and database need to be reconnected properly. If the database name, username, or password in your wp-config.php file is incorrect, WordPress won’t be able to connect to the database — and your site may show a blank screen or an error message.
Check DNS Settings
It could be a DNS issue — which means your domain name isn’t pointing to the right server yet. After switching hosting providers or changing domains, it can take some time for DNS changes to fully update (sometimes up to 48 hours). If the DNS is misconfigured or still pointing to your old host, visitors (and you) may not be able to reach the new site.
Check File Paths
Sometimes, the wp-content directory or other important files might not have transferred correctly. Verify that all WordPress files are properly uploaded to your new server.
4. Database Connection Errors
A database connection error in WordPress usually looks something like: “Error establishing a database connection.” This means WordPress is trying to talk to your website’s database — where all your content, settings, and user data are stored — but it can’t make the connection and the website doesn't load.
This issue is especially common after a migration or domain change, and it typically happens when the database details in your WordPress configuration file (wp-config.php) don’t match the actual database on your new hosting server. These details include the database name, username, password, and host (often “localhost”). If even one of these is incorrect, WordPress won’t be able to access the database, and your site won’t load.
Update wp-config.php File
Open the wp-config.php file in the root directory of your WordPress site and check the database name, username, password, and host. Ensure these details match those in your new hosting environment.
Check Database Server
If you’re using a different hosting provider, ensure the database host is correct. Often, the default database host is localhost, but some hosts may use a different server address.
5. SSL Certificate Errors
If your site is set up with HTTPS, you might encounter SSL certificate errors after migration or domain change. The SSL certificate may not match the new domain, causing mixed content issues (e.g., some content loading over HTTP while the page itself loads over HTTPS). To remedy this you can:
Install a New SSL Certificate
Ensure you’ve installed an SSL certificate for the new domain. Many hosting providers offer free SSL certificates via Let’s Encrypt, or you can purchase one from a provider.
Update URLs to HTTPS
Use a plugin like Really Simple SSL to automatically detect and fix mixed content errors and ensure all URLs are loaded over HTTPS.
Check for Mixed Content
If your website still loads some resources (images, scripts, etc.) over HTTP instead of HTTPS, you can use a plugin like SSL Insecure Content Fixer to resolve these issues.
6. Theme and Plugin Issues
After migrating your WordPress site to a new domain or web host, you might find that certain themes or plugins stop working properly — and this can be frustrating if everything seemed fine before the move. This usually happens because of a few behind-the-scenes issues that aren’t always obvious right away.
In simple terms, it's like moving a house — if you forget a few pieces of furniture (files), mislabel some boxes (paths), or try plugging old appliances into new sockets (compatibility), things just won’t work as they should. After a migration, it’s important to test your site thoroughly and check that all themes and plugins are installed properly, up to date, and fully compatible with your new setup.
Reinstall Plugins and Themes
If plugins or themes are not displaying correctly, try reinstalling them. Go to the Plugins or Appearance > Themes section of your WordPress dashboard and reinstall the affected plugins or themes.
Check Compatibility
Make sure your themes and plugins are updated to the latest versions, as older versions may not be compatible with your current WordPress installation or hosting environment.
Deactivate All Plugins
If your site is malfunctioning after migration, deactivate all plugins. If the site works, reactivate them one by one to pinpoint the problematic plugin.
7. Redirection Problems
Redirection issues are common when migrating a site or changing domains. You might try to visit your homepage or another page and find yourself being sent somewhere else unexpectedly — or stuck in a loop where the page keeps refreshing or bouncing back and forth without ever loading properly.
Update Site URL
Go to Settings > General in your WordPress dashboard and check the "WordPress Address (URL)" and "Site Address (URL)" fields. Make sure they reflect your new domain.
Use Redirects
If you’re moving to a new domain, you’ll need to implement 301 redirects to ensure visitors are directed to the correct pages.
Clear Caches
Clear your browser cache, and if you use caching plugins on your site, clear the cache there as well to ensure the redirects are updated.
8. Email Issues
After migrating your WordPress site to a new host or domain, you might run into unexpected email issues — such as contact form messages not sending, order confirmations not being delivered, or not receiving any emails from your site at all. Think of it like changing your return address but forgetting to tell the post office — your messages don’t get sent, or they land in the wrong place.
This is a common problem, especially if your site relies on WordPress to send emails for things like contact forms, user registrations, or eCommerce notifications. These issues often happen because the new hosting environment isn’t properly set up to handle email delivery, or it blocks outgoing emails for security reasons. In other cases, your WordPress settings may still be tied to the old domain, or your DNS records (like SPF or MX records) weren’t updated correctly during the migration. This can cause your emails to end up in spam folders — or not be delivered at all.
Check Email Configuration
Ensure that your wp-config.php file has the correct mail server configuration, particularly if you are using an SMTP plugin.
Use an SMTP Plugin
If you are facing email issues, use an SMTP plugin like WP Mail SMTP to configure email settings correctly and ensure your WordPress site can send emails properly.
