AJAX ERROR - Bad server response

[OmarMohamedHasan]

Every time I install the script I got the same error
Using xampp-windows-x64-8.2.4
Mod Rewrite enabled
PHP MYSQL PDO Extension enabled
PHP OpenSSL Extension enabled
PHP 8.2.4
Any help please?

Same issue for me and almost the same config as @OmarMohamedHasan (i.e Win10.0).
I'm not expert. Enabling 'browser developer tools' I can see line 105 in Page-cb.js

fetch(opt.url, { method:"POST", credentials:"include", body:data })

red underlined with opt_urlset as

http://localhost/iwashere/api/session/undefined/

where /api/session/undefined/ folder doesn't exist under base directory.
It seems something related to the user session.
I don't know if it helps.
Hope in @code-boxx too :)

You just need go to /lib and change the /jwt to /JWT
