Question

When I attempt to connect to QBO via the Consolibyte package I downloaded I get an error.
Error Code: internal_error

I have set up the config.php file as directed in the instructions and even got to the point of authorizing the application with Quickbooks but now when I navigate to the page it indicates that I am not logged in and when I click the "Connect to QuickBooks" button on the index.php page I get the error above. I'm not familiar enough with the process to know where to start troubleshooting this problem and any help would be greatly appreciated.

None of the tokens or OAuth credentials you have in your code match what you have in the screenshot.
Fix your tokens and OAuth values.
$token = 'f5ddd229b1d19b4153b8218b08b97897050f';
$oauth_consumer_key = 'qyprdYvvyNLq1om6FSw0xLebctZEAz';
$oauth_consumer_secret = 'KCLYZRgZ4LnHUB35AzvylxnH6c8CDCyjhva8I9Gp';
