SimpleXML is a PHP extension that makes it simple to manipulate and retrieve XML data.
All-in-One WP Migration requires SimpleXML to run some of its internal functions.
If you see this message, your server does not have the SimpleXML extension installed. Please contact your hosting provider to install the All-in-One WP Migration extension. Or you can consider using another cloud hosting provider, to run the All-in-One WP Migration application.
