Udelal jsem si an PC Server jedne hry pres Virtual box,portmapy,xampp na web a Hamachi.Na webu vse funguje i Server ale u Zbebricku a Registrace je chyba.U zebricku kde jsou pouice hracu je chyba nad nimy

    Notice: Undefined index: max in C:\xampp\htdocs\system\rangliste.php on line 17

a pod jmeny

    Notice: Use of undefined constant account_id - assumed 'account_id' in C:\xampp\htdocs\system\rangliste.php on line 52
