$selected = $_GET["sm"] will raise an undefined index notice when sm is not present in the query string. Use a default (e.g., $_GET['sm'] ?? ...) and/or isset() to avoid notices and ensure consistent submenu selection.

Suggested change

	$sselected = 1; $subtitle = $_i18n["login.submenu"]; $selected = $_GET[ "sm" ];
	$sselected = 1; $subtitle = $_i18n["login.submenu"]; $selected = $_GET[ "sm" ] ?? $sselected;

$_GET['tk'] is used without an isset()/default, which will trigger an undefined index notice when the parameter is absent. Consider defaulting to an empty string before base64_decode() (and handling false return values) so the page can render without warnings.

Suggested change

	<?php } $fields = " ".base64_decode( $_GET[ "tk" ] ); ?>
	<?php }
	$tk = isset( $_GET[ "tk" ] ) ? $_GET[ "tk" ] : "";
	$decodedTk = base64_decode( $tk );
	if( $decodedTk === false ){
	$decodedTk = "";
	}
	$fields = " ".$decodedTk; ?>

base64_decode($_GET['id']) is used to build an $_i18n lookup key directly from user input. If id is missing/invalid or the key doesn’t exist, this will produce undefined index notices and may surface unintended messages. Validate id against an allowlist of expected values (and fall back to a safe default message when the key is absent).

Suggested change

	<div align="center" class="msg">
	<div class="bl3">
	<div class="br">
	<div class="tl">
	<div class="tr2"><?=$_i18n[ "logine".base64_decode( $_GET[ "id" ] ) ]?>

	<br>
	<?php } $fields = " ".base64_decode( $_GET[ "tk" ] ); ?>
	<?php
	$loginMessage = "";
	if( isset( $_GET[ "id" ] ) ){
	$decodedId = base64_decode( $_GET[ "id" ], true );
	if( $decodedId !== false ){
	$allowedLoginMessageIds = array();
	foreach( array_keys( $_i18n ) as $i18nKey ){
	if( strpos( $i18nKey, "logine" ) === 0 ){
	$allowedLoginMessageIds[] = substr( $i18nKey, strlen( "logine" ) );
	}
	}
	if( in_array( $decodedId, $allowedLoginMessageIds, true ) ){
	$messageKey = "logine".$decodedId;
	$loginMessage = isset( $_i18n[ $messageKey ] ) ? $_i18n[ $messageKey ] : "";
	}
	}
	}
	$decodedTk = isset( $_GET[ "tk" ] ) ? base64_decode( $_GET[ "tk" ], true ) : false;

This <table> has two style attributes, which is invalid HTML and can cause inconsistent rendering (only the last style is applied). Combine these into a single style attribute (or move the width/text-align rules to CSS).

Suggested change

<table border="0" cellpadding="0" style="text-align: center;"

cellspacing="0" style="width:200px">

<table border="0" cellpadding="0" cellspacing="0" style="text-align: center; width:200px">

The form is declared as name="settings", but the focus script later references document.forms["login"], which will be undefined and throw a JS error. Rename the form (or update the script) so the form name/id matches what the script queries.

The markup opens a <form> but never closes it (and the surrounding <td>/<tr> structure also isn’t properly closed). Browsers may auto-correct this differently, potentially breaking submission/layout. Ensure the form and table cells/rows are properly closed before the outer </table>/</div>.
