The online server uses php 5.2.17 and cURL is enabled: libcurl/7.15.5 OpenSSL/0.9.8b zlib/1.2.3 libidn/ 0.6.5 * Thank you very much in advance. * Best regards, * [http://wordpress.org/plugins/facebook-feed-grabber/](http://wordpress.org/plugins/facebook-feed-grabber/) Viewing 8 replies - 1 through 8 (of 8 total) * Plugin Author [bonnerl](https://wordpress.org/support/users/bonnerl/) * (@bonnerl) * [12 years, 6 months ago](https://wordpress.org/support/topic/error-when-moving/#post-4226093) * Hi there, After some Googling of my own it does appear to be a server configuration issue. * The article linked to below is the most informative article I could find that might help you. - [How to fix Facebook Connect Error](http://www.tech-and-dev.com/2012/07/how-to-fix-facebook-connect-error.html) * Hope this helps you solve the problem! Please post back here with what you find! * Thread Starter [wkk](https://wordpress.org/support/users/wkk/) * (@wkk) * [12 years, 6 months ago](https://wordpress.org/support/topic/error-when-moving/#post-4226094) * Unfortunatelly I don’t have pretty much control of the online server (it’s from a hosting service). If the problem is due to a port blocked and hosting support offers me to use another one, where could I change this configuration? * Thank you very much for your help and also for your quick answers! * Regards, * Plugin Author [bonnerl](https://wordpress.org/support/users/bonnerl/) * (@bonnerl) * [12 years, 6 months ago](https://wordpress.org/support/topic/error-when-moving/#post-4226095) * You will need to file a support question with your host asking about the two ports. If the ports are blocked you will then have to ask them to open up the ports for you. I doubt you can use a different port as Facebook is going to expect you to be on ports 80 & 443. If you do the above and the ports aren’t blocked and you are on PHP 5.3+ then I would try [making a plugin](http://codex.wordpress.org/Writing_a_Plugin) that just has `curl_setopt( $ch, CURLOPT_IPRESOLVE, CURL_IPRESOLVE_V4 );` in it and see if that fixes the problem. * Thread Starter [wkk](https://wordpress.org/support/users/wkk/) * (@wkk) * [12 years, 6 months ago](https://wordpress.org/support/topic/error-when-moving/#post-4226133) * Hosting support confirmed me both ports are opened (since 80 is for HTTP and 443 for HTTPS/SSL protocols, it would be very strange if they were blocked). * The server is on php 5.2.17, I don’t know if that could be a problem if I write a plugin for this (me making plugins, what an adventure! xD). However, I see your plugin already includes that code in facebook-sdk/base_facebook.php line 987. So I don’t understand what would be the difference between this and a new plugin including also that line (I’m absolutely n00b about wp plugin coding, sorry xD). * Is there more documentation I could read for this? I noticed package facebook- sdk is not eclusive of your plugin (facebook-albums uses it also, and also isn’t working xD). So if it is a built-in code, normally the original source has more documentation. * This is a bit frustrating as I’m blind of what’s happening in the online server… * Thank you for all your ideas, I hope we could reach a solution! * Regards, * Thread Starter [wkk](https://wordpress.org/support/users/wkk/) * (@wkk) * [12 years, 6 months ago](https://wordpress.org/support/topic/error-when-moving/#post-4226172) * Well, I avoided the Uncaught CurlException by commenting line 977 of base_facebook. php. This just resolved a bad controlled error, but not the error itself (makeRequest returns false, so nothing is showed). * I’ve been googling for a while and I see many people is experienced this problem recently (a month ago, more or less). So I think it could be related to a problem with cURL versions. * – At localhost, I’m using PHP 5.3.8 and cURL 7.21.7 (it works!) – Online server uses PHP 5.2.17 and cURL 7.15.5 (ko, here…) * Just a couple of questions: · What’s your configuration for testing this plugin?· Do you have any documentation reference for facebook-sdk package? * Thank you very much in advance. I’ll keep investigating. * Regards, * Plugin Author [bonnerl](https://wordpress.org/support/users/bonnerl/) * (@bonnerl) * [12 years, 6 months ago](https://wordpress.org/support/topic/error-when-moving/#post-4226173) * The SDK is managed on GitHub at [https://github.com/facebook/facebook-php-sdk](https://github.com/facebook/facebook-php-sdk). * My development machine is running, - PHP 5.5.0 - cURL 7.21.4 * I also have the plugin on a production server running, - PHP 5.3.13 - cURL 7.22.0 * And a 2nd production server running, - PHP 5.2.17 - cURL 7.24.0 * Thread Starter [wkk](https://wordpress.org/support/users/wkk/) * (@wkk) * [12 years, 6 months ago](https://wordpress.org/support/topic/error-when-moving/#post-4226240) * Well finally I’ve made a jQuery solution, based on [https://github.com/pavelk2/social-feed](https://github.com/pavelk2/social-feed)( also from GitHub). I dind’t find a way to bypass cURL library, so I don’t know if that was actually the problem. But I’m pretty sure that it should be. Sorry I can’t help more =( * Anyway thank you for all your support. * Best regards. * Plugin Author [bonnerl](https://wordpress.org/support/users/bonnerl/) * (@bonnerl) * [12 years, 6 months ago](https://wordpress.org/support/topic/error-when-moving/#post-4226256) * Sorry I couldn’t be more helpful but I’m glad you found a solution!
