Well - i put storage-fs.phar into the plugin folder and press und "install" in osticket. The Window loading is popup, but after closing the plugin is not visible. The PHP log is showing no errors, but there is a DB-error:
[INSERT INTO ost_plugin SET installed=NOW() , install_path='plugins/storage-fs.phar', name='Attachments on the filesystem', isphar=1, version=0.3]
Unknown column 'version' in 'field list'<br /> <br />

#0 D:\Websites\xxx\osticket\include\mysqli.php(200): osTicket->logDBError('DB Error #1054', '[INSERT INTO os...')<br />
#1 D:\Websites\xxx\osticket\include\class.plugin.php(353): db_query('INSERT INTO ost...')<br />
#2 D:\Websites\xxx\osticket\scp\plugins.php(51): PluginManager->install('plugins/storage...')<br />
#3 {main}
After adding a column in DB (version/varchar(30)) everything seems fine.
