Not showing up in admin

Hi Zwoo,

All pages seem to give a 404 not found (for example: https://blok.aquasoftener.cz/zkusebni-stranka/).

Where did you put the blocks in the code?

Regards,
Harold

Sorry, .htaccess was off. Now its ok.
I put

"require": {
    "trendwerk/multiple-content-blocks": "3.2.2"
},

to composer.json

but under the page in admin is: “It doesn’t look like we can automatically initialize the blocks. Visit this page in the front-end and then try again.”

Disable HTTP Requests does not work.

I put

<div id="second-column" class="column"><php the_block ( 'Second column' ) ; ?></div>

to page template, but it is not work.

the_block( $name, array(
    'label'         => __( 'Admin label', 'text-domain' ),
    'type'          => 'one-liner',
    'apply_filters' => false,
) );

Iit works. But it is quite complicated to install.
