[SOLVED] Guzzle error message when accessing Administration pages

Hi.

We were running Joomla 3.6.5 / CB 2.1.0 / Kunena 5.0.4.1 on a "old" Ubuntu 12.04 LTS. But our server was hacked for Christmas (what a nice gift) and we decided to reinstall the server from scratch :
- fresh install of Ubuntu 16.4
- fresh install of Apache, MySQL, PHP 7.0.8, Joomla 3.6.5 ... components
- restore MySQL and WWW backups to keep our settings, history, ...





Every things work OK now except that we have an error displayed at the bottom of the Administration page :

This error is also displayed when we try to access CB Configuration page.

And we are not able to upgrade CB 2.1.0 to 2.1.2

I have found this threads :

But OpenSSL is already installed on our server :



What's wrong with our set up ?

Thanks.

Folks, please be sure to search. Searching the last part of an error or the keywords of an error will often given you accurate results on the first page. In this case the keywords used were simply "StreamAdapter.php on line 67".

Hi.

Thanks for the tip and the link

Installing php-curl do the trick !!

Thanks.

Thanks for the assistance - I did try the changes and they have resolved my error:

If still having issues try making the below change as a last resort to see if issue resolves.

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);

You don't need to make any changes to Guzzle. That change was a last resort quickfix. Your issue is from an incorrectly configured PHP7 server. Contact your host to ensure they've properly installed PHP7 (and push for them to redo it if it's still not working as cURL isn't setup right).

Hi, you are spot on!
The hosting company confirmed that the cURL was not enabled - it has now been correctly configured and all is working well - Thanks!
