Cannot retrieve access token

oauth
php

#1

I’m using the package https://github.com/J7mbo/twitter-api-php and am unable to retrieve an access token. I keep getting “this feature is temporarily unavailable”. If I change the token or verifier the message updates accordingly such as “Error processing your OAuth request: Invalid oauth_verifier parameter” so I know the API is working.

Can anybody please advise? It’s driving me insane and I’m out of ideas.
