Hello,
Plugin archive is ok. But MA plugin really has this problem on some servers and we contacted them a long time ago about this problem https://codecanyon.net/item/massive-addons-for-visual-composer/14429839/comments?page=79&filter=all#comment_18501820 Unfortunately, we get reports about this issue from our clients very often. As a rule, that solution from plugin author is helpful.
Regards
