Can’t load index.php [closed]

Hey!
I’m a complete newbie to php and e107 please bother with me.

So I finished the install process of e107 and configured everything. After the installation I got redirected to the index.php file but it won’t load! When I try to load up the index.php (with localhost/e107/index.php) I get this error message:

Fatal error: Uncaught ArgumentCountError: Too few arguments to function error_handler::handle_error(), 4 passed and exactly 5 expected in C:\xampp\htdocs\e107\class2.php:2559 Stack trace: #0 C:\xampp\htdocs\e107\e107_handlers\core_functions.php(135): error_handler->handle_error(8192, ‘Required parame…’, ‘C:\xampp\htdocs…’, 3034) #1 C:\xampp\htdocs\e107\e107_handlers\core_functions.php(135): require_once() #2 C:\xampp\htdocs\e107\class2.php(266): e107_require_once(‘C:\xampp\htdocs…’) #3 C:\xampp\htdocs\e107\index.php(58): require_once(‘C:\xampp\htdocs…’) #4 {main} thrown in C:\xampp\htdocs\e107\class2.php on line 2559

I tried to solve the problem myself but didn’t suceed.
I attached my class2.php file down below.

Thanks for any help! 🙂
