how to make the container block (table of content) in left sidebar?

Alright. We’ll wait for the credentials.

There's no way that I can do it?

Fernando's solution should work, so can you provide admin login so we can see what the issue is?

I created the block element then set it to Block element: left sidebar.
when i go to homepage in the wordpress top menu there's the elements that are active on the page.
I dont see the block element there.

Have you set the location of the element to frontpage?

Yes to "Best Streaming Equipment for Live Streaming" page

No, do NOT choose page > the page, make sure you choosefront page.

Thanks! it worked.
but can you explain why I needed to choose Front page and not the page name? what's the difference?

That's actually defined by WordPress.

When a page is set to front page, it uses the is_front_page() as condition.
