Switch to the Twenty Thirteen theme, delete this theme and install it again and see if it solves the problem. * If nothing works edit the **functions.php** file of this theme and comment or remove the following line * `require( $template_directory . '/core/includes/version.php' );` * This is only a temporary fix. * Thread Starter [Ameet Agarwal](https://wordpress.org/support/users/ameetagarwal/) * (@ameetagarwal) * [12 years, 6 months ago](https://wordpress.org/support/topic/warning-call_user_func_array-functioncall-user-func-array-6/#post-4339046) * Hay Jesin, thanks a million. The temporary fix provided by you has worked. This is an older version of the theme (1.5.9) There is no Child Theme created for this theme, and at this stage I am not in a position to update as it will change the look of the site. Will work on it when time permits. This is another great reason to use a child theme 😉 Thanks Again. * [Jesin A](https://wordpress.org/support/users/jesin/) * (@jesin) * [12 years, 6 months ago](https://wordpress.org/support/topic/warning-call_user_func_array-functioncall-user-func-array-6/#post-4339049) * Nice to hear that your problem is solved but 1.5.9 released way back in 06/07/ 2012 and so many things have changed since then. * I suggest you use a tool like quickdiff.com to find the differences between your theme and the original one and move those to a [child theme](http://codex.wordpress.org/Child_Themes) ASAP. * Else somewhere down the line a WordPress or a plugin update might break the entire site because WordPress might remove [deprecated functions](http://codex.wordpress.org/Category:Deprecated_Functions) in future releases. * Thread Starter [Ameet Agarwal](https://wordpress.org/support/users/ameetagarwal/) * (@ameetagarwal) * [12 years, 6 months ago](https://wordpress.org/support/topic/warning-call_user_func_array-functioncall-user-func-array-6/#post-4339053) * Yes Jesin, I am aware of that. I use Child Themes for all my WP setups, but this was done way back by someone else. The WP version was 2.7 and I updated it to 3.7.1 and also the plugins to their latest version, and this error popped up. My initial conclusion was that some plugin after update has caused this, so i disabled all plugins but the error remained. As i had not much time to fix this, I posted it on the forum and gladly you helped me out. * [Jitendra Mishra](https://wordpress.org/support/users/jitendra-mishra/) * (@jitendra-mishra) * [12 years, 5 months ago](https://wordpress.org/support/topic/warning-call_user_func_array-functioncall-user-func-array-6/#post-4339230) * Sorry, we do not monitor these forums, please use the official forum: * [http://cyberchimps.com/forum/free/responsive/](http://cyberchimps.com/forum/free/responsive/) * Thanks Viewing 5 replies - 1 through 5 (of 5 total) The topic ‘Warning: call_user_func_array() [function.call-user-func-array]:’ is closed to new replies. * ![](https://i0.wp.com/themes.svn.wordpress.org/responsive/6.3.7/screenshot.png) * Responsive * [Support Threads](https://wordpress.org/support/theme/responsive/) * [Active Topics](https://wordpress.org/support/theme/responsive/active/) * [Unresolved Topics](https://wordpress.org/support/theme/responsive/unresolved/) * [Reviews](https://wordpress.org/support/theme/responsive/reviews/) ## Tags * [call_user_func_array](https://wordpress.org/support/topic-tag/call_user_func_array/) * 5 replies * 3 participants * Last reply from: [Jitendra Mishra](https://wordpress.org/support/users/jitendra-mishra/) * Last activity: [12 years, 5 months ago](https://wordpress.org/support/topic/warning-call_user_func_array-functioncall-user-func-array-6/#post-4339230) * Status: resolved
