Writes event in database but doesnt display in log

Can you print the row stored from the DB here?

Sure:

3 testauthor updated Post profil_post_type_key The new Veranstalterprofil 69
7 127.0.0.1 1437051973

What is the testauthor value?

its the custom user role and in the column user_caps

You are need to register this role with AAL filter. You can see the filter here: https://github.com/KingYes/wordpress-aryo-activity-log/blob/master/classes/class-aal-activity-log-list-table.php#L77

Let’s me know if you are understand me.

yes, i know what you mean. i added the role to the ‘aal_init_caps’-filter:

$this->_caps = apply_filters(
			'aal_init_caps',
			array(
				'administrator' => array( 'administrator', 'editor', 'author', 'guest' ),
				'editor'        => array( 'editor', 'author', 'guest' ),
				'author'        => array( 'author', 'guest', 'testauthor' ),
			)
		);

But it didnt work unfortunately

Try this:

function wp7187051_aal_add_new_cap( $caps ) {
    $caps['testauthor'] = $caps['administrator'];
    return $caps;
}
add_filter( 'aal_init_caps', 'wp7187051_aal_add_new_cap', 30 );

Didnt work either unfortunately ??

What’s the role of this user? What he can to do? manage_options?

He has the following capabilities:

Dashboard:read;
Posts: publish_posts;edit_posts;edit_published_posts;
media:upload_files,
product: publish_product;edit_product;edit_published_product;
other cap: manage_product_terms, assign_product_terms

(product belongs to woocommerce)

Thank you

Try (for testing) to add him edit_pages cap, and see if you see his log.

Sorry, but didnt work either ??

Sorry for that, but try this:

function wp7187051_aal_add_new_cap( $caps ) {
    $caps['administrator'][] = 'testauthor';
    $caps['editor'][] = 'testauthor';
    return $caps;
}
add_filter( 'aal_init_caps', 'wp7187051_aal_add_new_cap', 30 );

Great. That worked. Thank you very much for your efforts.
