Hi,
In our website we have an option for users to login using twitter. It is working fine for the last 1 year, now it has an issue.
When I click on “Login with twitter”, it returns back to the website/callBackURL without showing the twitter login page.
I debugged the script and got this error “Authentication failed! Twitter returned an error. 403 Forbidden: The request is understood, but it has been refused.”
Can anyone help me on this error and provide me some suggesstions to solve this issue.
Thanks
