Blog posts have missing H1 but have H2?

Yes, my headings are in H2 and H1 is missing.
How do I implement H1 for blog posts or even replace H2 with H1?
Does that have to do with single.php which is blog template I believe?

Thanks

Yup you can change it from there … or check out source code because some themes has different layout pattern as well…And yes use only one H1 tag in your page while you can use more than H2 tag

What exactly I am to change?

There’s nothing wrong with using more than one H1 tag on a page…

@TechnicGeek - you would most likely need to look in your CMS’s templates and modify them there.
