Exclude an entire category on Related Post problem

Looks like the function is not entirely constructed correctly. Use this instead:

function jetpackme_filter_exclude_category( $filters ) {
    $filters[] = array(
        'not' => array(
            'term' => array(
                'category.slug' => 'archive-agenda',
            ),
        ),
    );
    return $filters;
}
add_filter( 'jetpack_relatedposts_filter_filters', 'jetpackme_filter_exclude_category' );

Thank
i have updated the code but nothing change …

Have you cleared the cache?

Absolutely

By any chance, is Archive Agenda your default category? If so, the process is a bit different, see the second snippet at https://jetpack.com/support/related-posts/customize-related-posts/#exclude-cats

Not, Archive-Agenda isn’t my default category ??

Are you using any sort of custom post types, or special category management plugins?

I don’t use custom post types, or special category management plugin.
I have desactived all plugins for test … same problem

Ok, we’ll need to take a closer look on this, please reach out to us via https://jetpack.com/contact-support/?rel=support
