When moving a WordPress site to a new domain or hosting provider, you may encounter issues with page URLs returning 404 errors. To resolve these errors, follow these steps:
1. Update the Site URL and Home options in the WordPress settings: Login to your WordPress dashboard and go to Settings > General. Update the Site URL and Home options to the new domain or hosting provider.
1. Update permalinks: Go to Settings > Permalinks and click Save Changes to update the permalinks. This will refresh the permalinks settings and resolve any old URLs pointing to the previous domain.
1. Redirect old URLs to new URLs: Redirect old URLs to new URLs using the .htaccess file or a plugin such as Redirection. This will ensure that visitors are automatically redirected from old pages to new pages without encountering a 404 error.
1. Update internal links: Update any internal links on your site to point to the new URLs. This can be done by using a plugin such as Velvet Blues Update URLs.
1. Check for broken links: Use a plugin such as Broken Link Checker to scan your site for any broken links that may be causing 404 errors.
By following these steps, you can resolve page URL errors during a WordPress site move and ensure that your site is fully functional on the new domain or hosting provider.
