Help with XAMMP

[JOROLOJI]

Hello,

I have this error:
Fatal error: Uncaught Error: Undefined constant "IBASE_COMMITTED" in C:\xampp\htdocs\firebirdwebadmin\inc\configuration.inc.php:137 Stack trace: #0 C:\xampp\htdocs\firebirdwebadmin\inc\script_start.inc.php(8): require() #1 C:\xampp\htdocs\firebirdwebadmin\database.php(9): require('C:\xampp\htdocs...') #2 {main} thrown in C:\xampp\htdocs\firebirdwebadmin\inc\configuration.inc.php on line 137

Can you help me install in XAMPP with Windows 10 64bits?
