Is it soap wsdl?

Yes, in Ubuntu for example it's the "php-soap" package. You need the SoapClient class.

When enabling the SolidCP module in WHMCS I would recommend to enable PHP errors in the admin area. Then you can see which PHP error occurs. After everything is working, don't forget to disable PHP errors, because it could be a security issue.

guys we dont know how to enable soap in php on windows, can anyone advise how please ?...

Hello,

In your PHP.ini you will need:

extension=php_soap.dll

Kind Regards,

But please note, that WHMCS is not supported on Windows servers:  http://docs.whmcs.com/System_Requirements

So therefore also the WHMCS SolidCP module is not tested on Windows.
