Admin bar showing twice when ESI blocks are enabled with wp_body_open used in theme

[LeonLiutas]

Hello,

When I enable ESI mode, the admin bar is showing twice.

This happens because in the file wp-content/plugins/litespeed-cache/src/esi.cls.php on line 362, the wp_admin_bar_render function is removed from wp_footer.

However, since WordPress 5.4, the wp_admin_bar_render function is attached to the action wp_body_open. If this function is not utilized by the active theme, the admin bar will be still attached to wp_footer.

I would suggest to remove the action wp_admin_bar_render first from the wp_body_open action. If that fails, remove it from wp_footer for backwards compatibility.

	// Add admin_bar esi
	if (Router::is_logged_in()) {
	remove_action('wp_footer', 'wp_admin_bar_render', 1000);
	add_action('wp_footer', array($this, 'sub_admin_bar_block'), 1000);
	}
