Fix for ‘Facebook error: Invalid OAuth access token’ error with API v2.3
-
Hi,
Today Facebook ended support for v2.2 of the API, and v2.3 includes a change to the format of access tokens which broke the ‘Add Link to Facebook’ plugin and generates the access token error above.
After a little debugging, I found a fix by editing the add-link-to-facebook-int.php file:
Replace
static function Process_fb_token($response) { $key = 'access_token='; $access_token = substr($response, strpos($response, $key) + strlen($key)); $access_token = explode('&', $access_token); $access_token = $access_token[0]; return $access_token; }with
static function Process_fb_token($response) { $key = 'access_token='; $access_token = json_decode($response)->access_token; // $access_token = substr($response, strpos($response, $key) + strlen($key)); // $access_token = explode('&', $access_token); // $access_token = $access_token[0]; return $access_token; }

Thank you @reddalek for the fix to this annoying problem.
It didn’t work for me. And after upgrade otpion for posting to pages is missing. Now I have in plugin admin panel information, that “This option is only available in Add Link to Facebook Pro”. The plugin maitainer didn’t reply form my mail sent few days ago. How can I get the Pro version?
@reddalek: Yes. I have these messages. I re-authorised the plugin and also tried the fix in PHP file that you’ve proposed. I think I should be looking for another plugin. I’d like something, which could produce FB post like on this image:

Or maybe someone could share ZIP package with Pro version of this plugin?
