I don’t know if this code is already hurting my site as I’m losing significant traffic. But there might be other factors. When I use the browser inspection tool, I see this code right after <!DOCTYPE html>: <html lang=”en-US prefix=”og:http://ogp.me/ns#”>. I know it’s the open graph protocol but their site is already in HTTPS. And their markup code is <html prefix=”og: https://ogp.me/ns#”>. Is there a way to get rid of it? Is it my Marketer theme that is causing it or a plugin?
But if I check Generatepress.com and other sites using GeneratePress, the OGP code is not there. Instead, I only see <html lang=”en-US”>.
