I used the correction file, what the administrator upload but it isn't solved the caracter problem and most manu items was disappeared. After I used this one:
/*----- added to split the menu name into first word and the rest */
//UTF-8 support for main menu titles modified by Marton Feovenyessy (
feovenyessy@gmail.com)
$tmp_tomb = mb_ereg('[w]+[s|.|?|!|[0-9]]+',$item->name,$regs);
$eredmeny_hossz=mb_strlen($regs[0]);
$focim=($eredmeny_hossz>0)?$regs[0]:$item->name;
$focim_hossz=mb_strlen($focim);
$teljes_hossz=mb_strlen($item->name);
$alcim_hossz=$teljes_hossz-$focim_hossz;
$alcim=($teljes_hossz>$focim_hossz)?mb_substr($item->name,$focim_hossz,$alcim_hossz,'utf-8'):"";
$tmp->name = "";
if (!empty($alcim)) {
$tmp->name .= '<span><![CDATA['.$focim.']]></span>';
$tmp->name .= '<span class="sub">' . $alcim . '</span>';
}
else
$tmp->name = '<span><![CDATA['.$item->name.']]></span>';
This one solved the caracter problem, but menu items disappeares yet.
Please help!!!!!!!!
