I analyzed my website: techiewiz.com and it says I only have 1 h1 tag despite the fact that my post titles are all h1.

Can anyone teach me how to solve this, please?

I think h1 are a must include for good on-page seo but maybe it is my theme function or WordPress acting funny.

I already provided the link so anyone who wants to run the SEO audit can see what I am talking about.

I need Google to read my h1 as post title and not h2 as post title.
