Hi This is Abdul Jabbar i am from pakistan as webmoney is an international payment so i think you should use multiple language instead of only russian anyways i have wordpress store
https://topgadet.storei am not a developer so for me the easyway is to itegerate plugins in wordpress but the problem is that your plugins are too old and not updated for years i think you seriously think about it or develop your own wordpress plugin instead of thirdparty
