This is just a guess and I’m really not sure, but it might have something to do with the Gravatar rating setting. * I had the beta version working flawlessly, it wasn’t till I made two changes that I received the error. Change the first was the addition of the “Super Cat Listener” plugin. Change the second was selecting a Gravatar rating under commenting options which previously remained unselected. * I was able to go back and delete the questionable plugin. Unfortunately I am notable to unselect a Gravatar rating and forced to choose one of the radio buttons supplied. * That said I could be completely wrong… please help! * Plugin Contributor [B.](https://wordpress.org/support/users/bandonrandon/) * (@bandonrandon) * [15 years, 5 months ago](https://wordpress.org/support/topic/plugin-wpbook-fatal-error-when-publishing-post/#post-1796200) * [@efab](https://wordpress.org/support/users/efab/) what verison of WPBook?

This issue still happens: Fatal error: Cannot redeclare wpbook_safe_publish_to_facebook() (previously declared in __FILE__/ publish_to_facebook.php:6) in __FILE__/publish_to_facebook.php on line 403. * I’m writing a simple script to get all of the unpublished posts, and publish them. For some reason, when I run wp_publish_post(), that error gets throw. What’s stranger is that error gets thrown on the third post. What does WPBook have to do with individual posts, especially in reference to publishing a single post? Why does that error get thrown when publishing posts? * [dasfisch](https://wordpress.org/support/users/dasfisch/) * (@dasfisch) * [14 years, 11 months ago](https://wordpress.org/support/topic/plugin-wpbook-fatal-error-when-publishing-post/#post-1796341) * To anyone having an issue, I figured out what the problem is. * NOTE: I am using WPBook 2.2.3! So any lines I put in here might be incorrect! * That said… * In the wpbook.php file, there is a function wpbook_publish_to_facebook() on line 1029. This is the function called through the hook, ‘draft_to_publish.’ This hook was causing the issue we were all seeing. The issue is every time I called wp_publish_post, that hook was running the wpbook_publish_to_facebook() function. Here’s where the problem lies: * ` if (!version_compare(PHP_VERSION, '5.0.0', '<')) { include(WP_PLUGIN_DIR .'/ wpbook/includes/publish_to_facebook.php'); } * All that code is doing is making sure we are running PHP5.0.0 or higher. This means, any time this function is called, we are going to reinclude the publish_to_facebook. php file. Ergo, we are going to have redefinition of wpbook_publish_to_facebook(). This will cause that error to get throw. * Here’s what the code should look like to ensure we don’t have redefinition errors: * ` if (!version_compare(PHP_VERSION, '5.0.0', '<')) { if(!function_exists('wpbook_publish_to_facebook')){ include(WP_PLUGIN_DIR .'/wpbook/includes/publish_to_facebook.php'); } } * Please make use of this as you see fit! It will clear up any redefinition errors you have with wpbook_publish_to_facebook()! * Cheers! * Plugin Author [John Eckman](https://wordpress.org/support/users/johneckman/) * (@johneckman) * [14 years, 11 months ago](https://wordpress.org/support/topic/plugin-wpbook-fatal-error-when-publishing-post/#post-1796342) * The other approach, which is what’s in the current dev version and just hasn’t yet been released, is just to use include_once rather than include. * Thanks for sharing your troubleshooting, and sorry that we haven’t pushed this code change out yet – it’s been sitting on the queue waiting for another release.( See the entry in the dev log from 6 weeks ago: [http://plugins.trac.wordpress.org/log/wpbook/](http://plugins.trac.wordpress.org/log/wpbook/)). I was waiting to bundle this change in with some others and then got sidetracked. * To those following along, this becomes an issue when multiple posts get published at the same time, which you often see on imports or syndication style models, like autoblogger. * [dasfisch](https://wordpress.org/support/users/dasfisch/) * (@dasfisch) * [14 years, 11 months ago](https://wordpress.org/support/topic/plugin-wpbook-fatal-error-when-publishing-post/#post-1796343) * That definitely be good a start. I would definitely add in the function_exists call, as well, in case some one decides to get crazy and ends up redefining the function. This will protect both aspects. * And not a problem at all. Gives me a chance to delve into the code more. I know how it can get maintaining code, especially when there’s a lot on your plate. * Thanks for the plugin, by the way!
