Hello @philippe,
Thanks for writing in! 
It seems I’m redirected to the homepage whenever I accessed the Wordpress login page. Kindly check if you have a code in the functions.php
of your child theme that blocks me from entering /wp-admin
. The code will look somewhat like the following:
function custom_blockusers_init() {
if ( is_user_logged_in() && is_admin() && !current_user_can( 'administrator' ) ) {
wp_redirect( home_url() );
exit;
}
}
add_action( 'init', 'custom_blockusers_init' ); // Hook into 'init'
Let us know once done so we can proceed with taking a closer look of your issue.
Thank you.
