[contactdravi]

I am using XAMPP which is working fine. Downloaded the ATutor from https://sourceforge.net/projects/atutor/

when is extract the ATutor.zip into htdocs of Apache C:\Users\conta\xampp\htdocs\atutor getting following error http://localhost:7780/ATutor/install/not_installed.php first i got this error. #0 C:\Users\conta\XAMPP\htdocs\atutor\install\not_installed.php(17): require() #1 {main} thrown in C:\Users\conta\XAMPP\htdocs\atutor\include\lib\constants.inc.php on line 123 [18-Jul-2024 19:05:01 Europe/Berlin] PHP Fatal error: Uncaught Error: Undefined constant "AT_CONTENT_DIR" in C:\Users\conta\XAMPP\htdocs\atutor\include\lib\constants.inc.php:121 Stack trace:

I fixed it by updating "AT_CONTENT_DIR" with define('WORKSPACE_FILE_PATH', AT_CONTENT_DIR . 'C:\Users\conta\XAMPP\htdocs');

later i got below error [18-Jul-2024 19:20:26 Europe/Berlin] PHP Parse error: syntax error, unexpected identifier "NUM_RELATED_TOPICS", expecting ")" in C:\Users\conta\XAMPP\htdocs\atutor\include\lib\constants.inc.php on line 124
