Hi, after some search about Plugins_Manager, know there are 2 versions which is php and tpl. I download the phpVMS-AirMail-3.1.zip and uploaded to Plugins_Manager. it shows,
Fatal error: Class 'ZipArchive' not found in /home/dragaorg/public_html/admin/modules/Plugins/Plugins.php on line 566
and I search in the plugins/upload directory and it does contain the zip file.
please advice, sorry for my bad english.
