Template Standart / delete Template / changed Template not working

Hi,
These are the default template options:

the Default Template is the file template-builder.php and can not be removed.
To remove the other ones:
Archives
Blank – No Header, no Footer
LayerSlider Blank Template
Add this code to the end of your child theme functions.php file in Appearance ▸ Editor:

function remove_layerslider_template( $templates, $theme, $post ) {
  unset( $templates['layerslider-blank'] );
unset( $templates['template-archives.php'] );
unset( $templates['template-blank.php'] );
  return $templates;
}

function adjust_template_filter() {
  remove_filter( 'theme_page_templates', [ 'LayerSliderClass', 'add_templates' ], 10, 3 );
  add_filter( 'theme_page_templates', 'remove_layerslider_template', 10, 3 );
}

add_action( 'init', 'adjust_template_filter' );

when you add this the meta box will not show in the backend because there is no choice to be made, the Default template will be used.
If you add your own template the meta box will then show, for example I created a file named my-template-blank.php with the Template Name: My Blank Template:

and now the meta box shows with this option:

If you also want to remove the LayerSlider blank template meta box:

Add this code to the end of your child theme functions.php file in Appearance ▸ Editor:

function remove_layerslider_meta_box() {
  remove_meta_box( 'ls-page-meta-box', 'post', 'side' );
  remove_meta_box( 'ls-page-meta-box', 'page', 'side' );
}
add_action( 'add_meta_boxes', 'remove_layerslider_meta_box', 11 );

Hi,
You are using a blog element on a page to show your bolg. you are not using a “template” you don’t need to remove the other “templates” and you don’t need to “add” templates.
The reason you page doesn’t show correctly is because to set the page as the default blog:

this is not the setting you want, I correct it for you:

I corrected your “template” error and now you page shows correctly.
Please remove your “templates” this is not the correct approach.

Best regards,

Hi,
I don’t know how you added the MEINUNG and Meinung_Seite templates, I don’t see them as I would expect, so you will need to remove them, not with the function above but however you added them in the first place. If you don’t remember how you added them then nevermind.

Best regards,
Mike

Hi,
Thanks this seems to be a WordPress Block Editor feature, but after much research I didn’t find a way to remove it.
I have asked the rest of the team for ideas on removing it, for now you can ignore it.

Best regards,
Mike
