No access to classmates from the “Share” block

I am developing a website. The domain name of the site knitting-master.ru. Put the block "Share" from Yandex. Option block with counters. To all soc. networks have access except classmates. When you click on Odnoklassniki, a window appears with the inscriptions - No access to the resource. Try later. Tried it later, nothing changes. My friend who put on his site the same block of the week for 3 before everything works. I contacted Odnoklassniki support service, they said that the reason was not from their side, but most likely from the developer of the buttons. Then I told them that I saw in the internet an article about the fact that Odnoklassniki sometimes do not give access due to some kind of violations. For example, the site may contain materials for adults. I have never had such materials, a site about knitted things, but maybe there are some other violations. After that, there was a pause from their side. I think they probably began to check for possible violations. Then the answer was that there are no violations on my site. And therefore it is not for their reason that there is no access. You need to contact the developers of the "Share" block, that is, Yandex. Help please solve this problem !!!
