"Could not find a PSR-18 compatible HTTP client" in WordPress, PHP SDK

Hi @leslye

Welcome to the Auth0 Community!

I’m not a PHP expert, but found a similar topic with a user reporting the same error → Problem with installation of auth0 - #3 by konrad.sopala

The error was raised because not all files were uploaded to the server. Can you check for that?

Thanks
Dawid
