Here are some steps that can be taken to resolve the issue:
- Check the error logs on the Linode server to see if any specific errors are being thrown that may indicate the cause of the issue.
- Verify that all the necessary dependencies such as PHP and MySQL are correctly installed and configured on the Linode server.
- Compare the server environment between the old server and the Linode server to ensure that all necessary settings are identical.
- Check the .htaccess file to see if any necessary rewrite rules were lost during the migration.
- Check the wp-config.php file to ensure that the database connection settings are correct.
- Check the PHP version of the Linode server, make sure it matches the PHP version of the previous server
- Try disabling all the plugins and switching to a default theme, this is to see if any of them are causing the issue.
If the problem persists, you may need to restore the site from a backup, or to rebuild the site completely.
