MODS package manager show a blank page and a download window with a file of mvpkg.php in synology in DSM6.2.2 DS918+

Hi, vletroye,
I'm using a synology DS918+ with DSM6.2.2-24992 updata 5
when I opened MODS package manager 0084,it displayed nothing and show a download window with a file of mvpkg.php
Some tutorials on the web said to change [https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js] to http://libs.baidu.com/jquery/2.0.0/jquery.min.js or http://ajax.aspnetcdn.com/ajax/jQuery/jquery-3.2.1.min.js in file mvpkg.php
But it doesn't work
Then I upgraded MODS package manager 0084 to 0088, and it doesn't work too.
So How can I fix this?

Thanks
Ted
