Error We were unable to connect your account. Please contact your system administratorCause
A 2018 change to the Twitter APIs altered the configuration of callback URLs in Twitter apps. Because of this, you must specify the precise full URL to the Twitter API callback file to interact with your WHMCS installation.
Solution
To resolve this issue:
- Go to apps.twitter.com.
- Log in to your Twitter account.
- Select your WHMCS sign-in app from the list.
- Go to the Settings tab.
- In the Callback URLs section, replace the current single entry with the following three entries, replacing
http://demo.whmcs.com/whmcs/with the URL of your WHMCS installation.
http://demo.whmcs.com/whmcs/index.php
http://demo.whmcs.com/whmcs/index.php/auth/provider/twitter_oauth/callback
http:///demo.whmcs.com/whmcs/auth/provider/twitter_oauth/callback
6. Click Save Changes.
7. In WHMCS, activate Twitter again at Configuration > System Settings > Sign-In Integrations (or, prior to WHMCS 8.0, Setup > Sign-In Integrations).
