The K2 Media Manager cannot be opened, primarily because Google's CDN is loaded in K2, and Google's services are not working properly at home. Therefore, after knowing the reason can be changed to Baidu or Microsoft CDN Service.
1. Open: administrator/components/com_k2/helpers/html.php file, line 70th or so:
if ($mediaManager) {//$document->addscript ('//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js '); Comment out Google's CDN. Load Baidu's. $document->addscript ('//apps.bdimg.com/libs/jquery/2.1.4/jquery.min.js ');}
2. Open: administrator/components/com_k2/views/media/view.html.php file, line 23rd:
$document->addstylesheet ('//ajax.googleapis.com/ajax/libs/jqueryui/1.8/themes/smoothness/jquery-ui.css ' ); modified to: $document->addstylesheet ('//apps.bdimg.com/libs/jqueryui/1.10.0/themes/smoothness/jquery-ui.css ' );
