  • Enable openssl extension

    --PATH E:\laragon\bin\php\php-8.0.16-Win32-vs16-x64\php.ini
    extension=openssl
    
    0

    Enable openssl extension by removing the ; from the ;extension=openssl in php.ini file.

    Find ;extension=openssl in php.ini file and remove ; from it or just place extension=openssl in case you did not find the ;extension=openssl in php.ini.

    Additional Note:

    File path may be different.
