Transferring a WordPress site to new hosting can cause settings loss if files or databases aren't properly backed up. Use reliable migration tools to ensure a seamless transfer.

When switching hosts, make sure to export all files and the full database including settings. Common hiccups: database credentials mismatched in wp-config.php, missing upload directory, permalink or .htaccess errors and plugin/theme incompatibilities. Double-check database name/host, re-save permalinks, ensure correct file permissions, and confirm all media and plugin/theme files are copied properly.
