The reason for my query is on the header in the new OJS version (v. 3).
It is displayed correctly in the browser, but at the time of apercer that header in the search engine (google), appears in front of the content Page header - (and then what I really have put in header within the control panel).
Of course @NateWr , but now that I check it does not appear in the google search now what it indicated. If it reappears, I reopen this post. Thank you very much for your interest in my case.
