@LeonidS Thank you sir for your response.

I don't know what studio you are talking about. How can I get this studio and use it? Can tell me more about this, please!?

I am using XAMPP's latest version, which is using PHP 8.x. So I guess the PHP version isn't the problem. Also while installing the script it didn't say anything about the PHP version because all the requirements for this script were fulfilled.

Although it had shown me 2 warnings related to 2 modules. But it was optional and I didn't need those modules in XAMPP to test the script.

Now after installing, I am seeing an error link below the pictures.
