Title: Warning: call_user_func_array parameter issue Last modified: May 19, 2018 --- # Warning: call_user_func_array parameter issue * Resolved [Jeff Lambert](https://wordpress.org/support/users/lambje/) * (@lambje) * [7 years, 10 months ago](https://wordpress.org/support/topic/warning-call_user_func_array-parameter-issue/) * I’m looking at the error log for a multisite (3 sites) that I’m performing maintenance on today. Each day I get the following error repeated 6 times: * [16-May-2018 13:39:04 UTC] PHP Warning: call_user_func_array() expects parameter 1 to be a valid callback, class ‘BackWPup_Cron’ does not have a method ‘update_message’ in /home/markengl/public_html/wp-includes/class-wp-hook.php on line 286 * I’m running v3.4.5 of BackWPup and v9.4.5 of WP. * While unrelated, this multisite is the same one that I was getting 3 backups created each day instead of the 1. I did put in a fix from that thread, which fixed that issue. * Thanks for the plugin! * Cheers, * Jeff Viewing 5 replies - 1 through 5 (of 5 total) * [happyAnt](https://wordpress.org/support/users/duongcuong96/) * (@duongcuong96) * [7 years, 10 months ago](https://wordpress.org/support/topic/warning-call_user_func_array-parameter-issue/#post-10304239) * [@lambje](https://wordpress.org/support/users/lambje/) Could you please give me your PHP info? go to BackWPUp -> Settings -> Infomation -> and press “Get debug info” * Thread Starter [Jeff Lambert](https://wordpress.org/support/users/lambje/) * (@lambje) * [7 years, 10 months ago](https://wordpress.org/support/topic/warning-call_user_func_array-parameter-issue/#post-10306651) * Sure [@duongcuong96](https://wordpress.org/support/users/duongcuong96/): * WordPress version: 4.9.5 BackWPup version: 3.4.5 PHP version: 7.0.30 (64bit) MySQL version: 5.6.38 cURL version: 7.59.0 cURL SSL version: OpenSSL/1.0.2o WP- Cron url: [https://greencomplianceplus.markenglisharchitects.com/wp-cron.php](https://greencomplianceplus.markenglisharchitects.com/wp-cron.php) Server self connect: Response Test O.K.
