How do i change my text in the activation email i want to translate it and write my own text. I tried editing the file: plugins/buddypress/bp-core/bp-core-filters.php I changed the text in this function but it didn’t change the activation email function:

‘bp_core_activation_signup_blog_notification( $domain, $path, $title, $user, $user_email, $key, $meta ) {

// Send email with activation link.
$activate_url = bp_get_activation_page() .”?key=$key”;
$activate_url = esc_url( $activate_url );

$admin_email = get_site_option( ‘admin_email’ );

if ( empty( $admin_email ) )
$admin_email = ‘support@’ . $_SERVER;

$from_name = ( ” == get_site_option( ‘site_name’ ) ) ? ‘WordPress’ : esc_html( get_site_option( ‘site_name’ ) );
$message_headers = “MIME-Version: 1.0n” . “From: “{$from_name}” n” . “Content-Type: text/plain; charset=”" . get_option( ‘blog_charset’ ) . “”n”;
$message = sprintf( __( “Gracias por registrarse al mejor redsocial de Guatemala! Para completar la activacion de su cuenta, por favor haga clic en el siguiente enlace:nn%1$snnnnDespues de activar, puede visitar su sitio aqui:nn%2$s”, ‘buddypress’ ), $activate_url, esc_url( “http://{$domain}{$path}” ) );
$subject = ‘ ‘ . sprintf(__( ‘Activate %s’, ‘buddypress’ ), esc_url( ‘http://’ . $domain . $path ) );’

But nothing happened am i editing the wrong file? I am also using the plugins: BP Auto Login on Activation and Welcome Pack. Can it be that the email that is sent is contained in there?

Thank you guys for your help in advance!
