I have de same problem

Hello, dear friends. I had the same problem and found that bug is hidden here in the file class.facebook.plugin.php inside of GetProfile function at this line:

$Contents = file_get_contents($Url);
The problem mostly is not in vanilla forum, but in PHP configuration. It should be built with OpenSSL support to transfer data via https protocol ($Url in this case points to https facebook site). But this function is deprecated and it's bit strange why developers use it instead of curl functions. Moreover there are a lot of curl calls in this file. Because of that on some configurations this bug exists, on others don't.

To make it work correctly, try to change this line to:

$Contents = $this->file_get_contents_curl($Url);
Of course, my dear friends, you have to add the function file_get_contents_curl inside of the file. Put the following code after the GetProfile function:

function file_get_contents_curl($url) { $ch = curl_init($url); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false); curl_setopt($ch, CURLOPT_HEADER, 0); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); //Set curl to return the data instead of printing it to the browser. curl_setopt($ch, CURLOPT_URL, $url); $data = curl_exec($ch); curl_close($ch); return $data; }
It should work now! I hope you'll enjoy vanilla forums.

If it doesn't work, please ensure that OpenSSL feature is enabled for cURL.

Hi Alibaba31337,

I am trying your solution.

Where exactly did you place the second part of the code ?

Is it under: "$Contents = $this->file_get_contents_curl($Url);" ?

As you can see I am not a developer

Thanks

second part of the code you just can place after GetProfile function, after the closing curly bracket ("}"). Something like:
function GetProfile { // some code goes here, where you have to change the line } // <-- closing curly bracket of GetProfile function // second part of the code function file_get_contents_curl($url) { // bla-bla }

I'll mark your P.S. as a suggestion for next release, might be a bugfix by then, but we'll see. I'll close this thread now :-)
