Enabled and setup correctly are two different things. Could be as simple as the cURL PHP module not being compiled correctly. If you're on localhost there's nothing I can really suggest as we don't support localhost environments and expect anyone running them to understand setting up servers; I'm using wampserver which is working fine locally. If on hosted server then please contact your host. All other users with your exact issue resolved it by having cURL fixed. The error you're getting is just a symptom of that problem.

After reinstall all server when i trying to access the CB Configuration, I get the following error:

Argument 2 passed to GuzzleHttp\Adapter\StreamAdapter::createResponseObject() must be of the type array, null given, called in /var/www/joomla/cav/libraries/CBLib/GuzzleHttp/Adapter/StreamAdapter.php on line 67


after i try

IN: libraries/CBLib/GuzzleHttp/Adapter/StreamAdapter.php
ON: Line 62
FROM:
$stream = $this->createStream($request, $http_response_header);
TO:
$http_response_header = array();
$stream = $this->createStream($request, $http_response_header);

.... my problem with CBconnect is solved... Great

BUT when i want open Comunity Builder any plugin i get

Notice: Undefined offset: 1 in C:\Apache24\htdocs\verbis\libraries\CBLib\GuzzleHttp\Adapter\StreamAdapter.php on line 86
Notice: Uninitialized string offset: 0 in C:\Apache24\htdocs\verbis\libraries\CBLib\GuzzleHttp\Subscriber\HttpError.php on line 30

I have PHP 7.1.8 V14 (i tested with 7.0.22 ...same result) . and Apache 2.4 64 V14. Latest Joomla 3.6.5

without change StreamAdapter.php i get when i try link facebook with any account in Joomla
Argument 2 passed to GuzzleHttp\Adapter\StreamAdapter::createResponseObject() must be of the type array, null given, called in C:\Apache24\htdocs\verbis\libraries\CBLib\GuzzleHttp\Adapter\StreamAdapter.php on line 67


I thing that you are not tested Community Builder for PHP 7 enough

I reinstall PHP and Apache 24 to 2.4 32 V11 and PHP 5.6 V11 and CB Connect is OK without modify StreamAdapter

I thing that you are not tested Community Builder for PHP 7 enough

I've been using PHP 7 every day for nearly a year now. I am unable to confirm this issue. Other users with your issue have contacted their host and was resolve through their host. Either due to cURL not being installed or configured correctly or some other related server problem. The issue is cURL isn't returning the header resulting in a null response instead of the expected array, which is causing the error you see.

We can not upgrade Guzzle yet as doing so requires pushing our minimum PHP requirements, which we can not do at this time. We will, in the near future, be pushing minimum PHP requirements to 5.6 allowing us to update Guzzle for better compatibility. If you can not get this resolved on a host level then switch to PHP 5.6 for the time being as I have no workarounds to suggest, sorry.
