Question

I am new to openinvitor. I have downloaded PHPizabi 1.9.6. From Here in that I am running example_list.php file using this i am able to get contacts from gmail but i am not able to get contacts from YAHOO. I am getting error "Login failed. Please check the email and password you have provided and try again later !".

When I am login from Yahoo getting login successfully, but not through this plugin.
