wordpress 404 page after migration

To troubleshoot a WordPress 404 page error after migration, follow these steps:

  1. Check the Permalinks Settings: Go to the WordPress dashboard and navigate to Settings > Permalinks. Ensure that the permalink structure is set correctly. If it's not, choose a different structure and save the changes.

  2. Update the .htaccess file: Sometimes, the .htaccess file may not update during the migration process, causing 404 errors. To fix this, access the root folder of your WordPress installation and locate the .htaccess file. Open it and save the file again without making any changes. This will update the file and clear any potential issues.

  3. Reset the WordPress Rewrite Rules: In some cases, the rewrite rules may not be properly updated after migration, leading to 404 errors. To reset the rewrite rules, you can install and activate the "Flush Rewrite Rules" plugin. Once activated, visit the WordPress dashboard and navigate to Settings > Permalinks. Click on the "Save Changes" button without making any changes. This will flush and reset the rewrite rules.

  4. Check the Database for Broken Links: After migrating your WordPress site, there might be broken links in the database. To fix this, you can use a plugin like "Broken Link Checker" to scan and fix any broken links. Install and activate the plugin, then go to Tools > Broken Links. Follow the instructions to scan and fix any broken links.

  5. Update the Site URL: If the site URL was not properly updated during migration, it can cause 404 errors. To fix this, access the WordPress database using phpMyAdmin or a similar tool. Locate the wp_options table and look for the siteurl and home rows. Update the values to match the new URL of your migrated site.

  6. Check for Plugin or Theme Conflicts: Sometimes, conflicts between plugins or themes can cause 404 errors. Disable all plugins and switch to a default WordPress theme (like Twenty Twenty-One). If the 404 error disappears, then you know it's caused by a plugin or theme. Re-enable them one by one until you identify the culprit and either update or replace it.

By following these steps, you should be able to troubleshoot and resolve the WordPress 404 page error after migration.
