Title: Callback error after last update Last modified: February 4, 2018 --- # Callback error after last update * Resolved [icks13](https://wordpress.org/support/users/icks13/) * (@icks13) * [8 years, 4 months ago](https://wordpress.org/support/topic/callback-error-after-last-update/) * Hello, * recently I had to update a couple of plugins by uploading their zip file. Every time the uploading was going fine and I was able to correctly activate the plugin, however there were always the following message error: * Warning: call_user_func_array() expects parameter 1 to be a valid callback, array must have exactly two members in …/ccwgnwmyuq/public_html/wp-includes/class-wp- hook.php on line 288 * After a lot of app testing, disable and enable plugins (I have 39 activated) I’ve found out that the problem is related with your plugin. Once I’ve deleted Feed Them Social, I was able to install/update plugins via zip file without get the error message above. * Now, the plugins works and in my case Feed Them Social works too (I just use it as Pinterest Board Feed) but we don’t wanna find out what kind of other complications may trigger, so if you could fix it:) * thank you Viewing 10 replies - 1 through 10 (of 10 total) * Plugin Author [slickremix](https://wordpress.org/support/users/slickremix/) * (@slickremix) * [8 years, 4 months ago](https://wordpress.org/support/topic/callback-error-after-last-update/#post-9937212) * Hey [@icks13](https://wordpress.org/support/users/icks13/), Sorry for the troubles! * Can you please copy and paste to me the Report from the System Info page of our plugin?

Additionally the message should not appear if you have your wp_debug mode set to false in the wp-config.php file on the root of your wordpress install. For those who don’t already know, generally wp_debug mode is only set to true if you are developing the site. Let us know if you have this set to false already and are still seeing the message. I believe we should have a fix for this in our next update. * Spencer * Plugin Author [slickremix](https://wordpress.org/support/users/slickremix/) * (@slickremix) * [7 years, 12 months ago](https://wordpress.org/support/topic/callback-error-after-last-update/#post-10425768) * I’m not positive yet but I did notice an add_action call on line 72 on the main file of our plugin feed-them.php in our latest version 2.4.2… it says…. * `add_action('upgrader_process_complete', array(self::$instance, 'fts_upgrade_completed', 10, 2));` * I believe the ) bracket being out of place is causing the warning message. * `add_action('upgrader_process_complete', array(self::$instance, 'fts_upgrade_completed'), 10, 2);` * [lindag99](https://wordpress.org/support/users/lindag99/) * (@lindag99) * [7 years, 11 months ago](https://wordpress.org/support/topic/callback-error-after-last-update/#post-10458286) * Hi Spencer, I have this message on every site I have “Feed Them” installed. If I remove that extra ), do you think it will go away? Or are you fixing it in the next update? Thanks!

Try coping the code below and replace it with the other as mentioned above…. Let me know if this works for you on one site and I will make an update to correct the issue for good 🙂 * `add_action('upgrader_process_complete', array(self::$instance, 'fts_upgrade_completed'), 10, 2);` * Spencer * [Wp_begginer_pri](https://wordpress.org/support/users/wp_begginer_pri/) * (@wp_begginer_pri) * [7 years, 10 months ago](https://wordpress.org/support/topic/callback-error-after-last-update/#post-10576901) * [@icks13](https://wordpress.org/support/users/icks13/) * Hi ICKS, * I am writing here as my client wanted to get in touch with you since both of you experienced a same plugin “loud and clear guy”- Does it ring a bell? 😉 * Therefore, I was wondering if it is possible for you to share a professional email ID which I can pass on to my client who has read your posts in other forums and wanted to discuss a few things with you, as just like you, they are fed up trying to hammer EU laws to the ‘loud and clear’ team if you get me 😉 * They would be very grateful if I can put you in touch with them. They are wonderful folks. * Best Regards. * Pri * [@slickremix](https://wordpress.org/support/users/slickremix/) : Sorry for hijacking this but wp has no system to connect with other users yet and it can be so helpful sometimes 🙂 Viewing 10 replies - 1 through 10 (of 10 total) The topic ‘Callback error after last update’ is closed to new replies. * ![](https://ps.w.org/feed-them-social/assets/icon-256x256.jpg?rev=998039) * [Feed Them Social - Social Media Feeds, Video, and Photo Galleries](https://wordpress.org/plugins/feed-them-social/) * [Frequently Asked Questions](https://wordpress.org/plugins/feed-them-social/#faq) * [Support Threads](https://wordpress.org/support/plugin/feed-them-social/) * [Active Topics](https://wordpress.org/support/plugin/feed-them-social/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/feed-them-social/unresolved/) * [Reviews](https://wordpress.org/support/plugin/feed-them-social/reviews/) * 10 replies * 6 participants * Last reply from: [Wp_begginer_pri](https://wordpress.org/support/users/wp_begginer_pri/) * Last activity: [7 years, 10 months ago](https://wordpress.org/support/topic/callback-error-after-last-update/#post-10576901) * Status: resolved
