I am new to salesforce, and when I try to login the site from
https://login.salesforce.com/?startURL=%2Fsetup%2Fsecur%2FRemoteAccessAuthorizationPage.apexp%3Fsource%3D... it redirects to
https://developer.salesforce.com/500 after checking my username and password.
I am getting the following error page.
We're sorry, but something went wrong. If you are the application owner check the logs for more information.
