Load more button not working on post category pages

Hi there,

Are you referring to the read more button not showing?

If so it looks like you are using the custom excerpt metabox:

So this code is needed:

Hi Leo,

Activated: https://wordpress.org/plugins/advanced-excerpt/

I pasted:

Not displayed well:

You don't need that plugin.

The excerpt metabox comes default with WordPress:
https://www.screencast.com/t/w520Lm0XYQM

The code needs to be added using one of these methods below and not a hook:
https://docs.generatepress.com/article/adding-php/

ADDING THIS:

add_filter( 'wp_trim_excerpt', 'tu_excerpt_metabox_more' );
function tu_excerpt_metabox_more( $excerpt ) {
$output = $excerpt;

if ( has_excerpt() ) {
$output = sprintf( '%1$s <p class="read-more-button-container">%3$s</p>',
$excerpt,
get_permalink(),
__( 'Read more', 'generatepress' )
);
}

return $output;
}

THE RESULT IS:

The snippet has been deactivated due to an error on line 3:
Cannot redeclare function tu_excerpt_metabox_more.

I have a problem in JP langage:
https://farmamondo2020.factorybank.it/ja/category/farmamondo-news-ja/corporate-news-ja/

EXCERPT Work fine:
https://farmamondo2020.factorybank.it/category/farmamondo-news/corporate-news/
https://farmamondo2020.factorybank.it/ru/category/farmamondo-news-ru/corporate-news-ru/
https://farmamondo2020.factorybank.it/es/category/farmamondo-news-es/corporate-news-es/

In RU EN ES experpt work fine in JP no !?
And the BT read more ... nothing

That error means that PHP function is already added to the site somewhere.
