@Roman Your question does not relate to this thread thus the solution is not working for you. It would be easier for us to help you if you post a new topic if your question is a new one. However, here goes your solution. In the dashboard, go to Appearance->Theme Options->Design Options Tab->Custom CSS. Paste the following css and click on ‘Save all Changes’.
.hgroup-wrap {
display: none;
}
Hope this helps. 🙂
