How I can add H1 title?

You can use a Block element and Generateblocks to add dynamic H1 title to the pages that are missing H1.

How is can add bread crumbs to forums pages?

GP doesn't have a breadcrumbs function, it's better to reach out to BBPRESS's support for this.

Let me know if you need further assistance :)

Thanks for your answer. But I can’t understand where exactly I must fix this.

I trying hero, but here readu H1 title…

You'll want to add H1title to the pages that the report indicates in which H1is missing.

So they are the blog page, the frontpage, and forum pages.

You can try to add these pages to the location of the Archive header block ( block - page hero).

Example as below (Note: I don't have BBpress on my test site, so I can't demonstrate it here)

Or create a new block - page hero element and assign it to these pages if you want to apply new style.

Thanks you, but I think will be easy change template.
