How can I correctly specify the redirect_uri for a widget for publishing to a user's page from external Odnoklassniki applications?

Question

Social media

There is a link to post in the feed:

http://connect.ok.ru/dk?st.cmd=WidgetMediatopicPost&st.app={appId}&st.attachment={attachment}&st.return=http%3A%2F%2Fmysite.vi%2Fitems%2FokPost%3Fid%3D31&st.popup=on&st.utext=on

After the entry is posted, only the post ID is issued, but there is no redirect back to the site. Tried with different links and coding but the result is always the same.
The application has been approved by the social network.

Answer 1

There was a problem with the widget, fixed.
Thanks for the report.
