[SOLVED] undefined function dom_import_simplexml()

[Ampersand]

Code:

Fatal error: Uncaught Error: Call to undefined function dom_import_simplexml() in ../admin/inc/basic.php:216 Stack trace:
    #0 ../admin/inc/plugin_functions.php(215): SimpleXMLExtended->addCData('anonymous_data....')
    #1 ../admin/inc/plugin_functions.php(101): create_pluginsxml()
    #2 ../admin/inc/common.php(344): include_once('...')
    #3 ../admin/index.php(17): include('...')
    #4 {main} thrown in ../admin/inc/basic.php on line 216

Quick check:

PHP Code:

if (function_exists('simplexml_import_dom')&&function_exists('simplexml_load_file')&&function_exists('simplexml_load_string')) {
    echo "simplexml functions available.<br />\n";
} else {
    echo "simplexml functions not available.<br />\n";
}
//simplexml functions available. 


This happens on ../admin/index.php with a site migrated to a 7.2 server. Did I missed anything during the process or still some module missing?
