System stopped checking Yandex. I've deleted search engines (Yandex RU and Yandex UA), than added again. Status of keywords "checking..." and this situation is already during more than an hour... Nothing happens...
Dear Prosto,

We had problems with Yandex. They changed not only index, but also HTML in the search result. We saw several variants of the HTML output in different regions. Because of this, it took us more time to fix all mistakes in the parsing algorithm. Now position checking in Yandex should work correctly.
