Answer 1

I had same problem.
Here’s what I did wrong that you might have done:

When I went to this page:
https://github.com/facebook/facebook-php-sdk/tree/master/src
to download facebook.php, base_facebook.php, etc.

I right-clicked and did “Save Link As” not realizing that I wasn’t saving what I thought I was saving.

SOLUTION: click those links and THEN copy and paste the code into facebook.php, etc.
