Fatal error: Uncaught SoapFault exception: [HTTP] Server Error in D:\apache2triad\htdocs\local\z\BetfairAPIFramework \classes\betfairutility.class.php:77 Stack trace: #0 D:\apache2triad\htdocs\local\z\BetfairAPIFramework \classes\betfairutility.class.php(77): SoapClient->__doRequest('__doRequest('__call('login', Array) #3 D:\apache2triad\htdocs\local\z\BetfairAPIFramework \classes\betfairglobalapi.class.php(116): SoapClientExtended->login(Array) #4 D:\apache2triad\htdocs\local\z\BetfairAPIFramework \example\index.php(70): BetfairGlobalApi->betfair_api_login('my username', 'my password', 82, false) #5 {main} thrown in D:\apache2triad\htdocs\local\z\BetfairAPIFramework \classes\betfairutility.class.php on line 77

 

check for the http.conf in your apache, search for soap extension. check if its commented or not..
