Contact Importer in PHP (Open Inviter Technology)
<p>I am using contact importer in PHP (by open inviter technology).
I am able to successfully import contacts from g-mail and hot-mail.
But I am facing some problems in yahoo and twitter.
My website url, where I am using contact importer is :</p>

<p><a href="http://21flats.com/beta/contacts_importer/OpenInviter/example.php?url1=http://21flats.com/beta/projects/16/26/Own_a_villa_in_Himalayas_an_attractive_price.html&amp;project=16" rel="nofollow">http://21flats.com/beta/contacts_importer/OpenInviter/example.php?url1=http://21flats.com/beta/projects/16/26/Own_a_villa_in_Himalayas_an_attractive_price.html&amp;project=16</a></p>

<p>In some of yahoo mails it imports contacts successfully, but in some emails it shows error
'Login failed. Please check email and password you have provided and try again later!'</p>

<p>The emails from which I can import contacts successfully are  'testing_1988@ymail.com'  and 'sushilkandola1988@yahoo.com'. Both of these id's are newly created.
But some of old id's are not importing contacts e.g 'testingdeveloper@ymail.com'</p>

<p>And for Twitter it shows an error 'Unable to get contacts !'</p>

<p>Please help me for this.</p>
