XF 2.0 Upgrade system login?

[philippm]

Hey Xenforo forum!
I'm new here and I hope I'm in the right section - I got a real problem!
I ran into an issue while trying to create an API / REST API for your software.
After I set up the Autoloader

XenForo_Autoloader::getInstance()->setupAutoloader(ROOT . '/library');

Xenforo redirects to me a page with the title „upgrade system login“ (check attachment)? What do I need to fix this problem? Is anything missing or do I set up Xenforo wrong?

Thank you in advance!

That code of yours is from XF1.
