How to integrate FB into the site?

Question

PHP

In general, I do login in ovncloud.
I came across this error
Fatal error: Cannot redeclare class facebook\facebookrequestexception in C:\xampp\htdocs\owncloud\core\registration\fb\src\Facebook\FacebookRequestException.php on line 38
tried to fix the require-ami but nothing happened.

Answer 1

well, what's the problem...
where the file with the class is included 2 times, well, or different files with the same classes... the debugger was invented for this...
