Maybe you installed plugins or edited snippets? Can you show the settings of snippets? * Thread Starter [cristoto](https://wordpress.org/support/users/cristoto/) * (@cristoto) * [5 years, 9 months ago](https://wordpress.org/support/topic/code-not-working-logout/#post-13057741) * Thank you for your quick answer. * I didn’t install any new plugin, I only updated some plugins include Woody Snippets. * I have differents snippets. I show you my login snippet. * [My snippet code](http://collabedit.com/44wfv) * [Temyk](https://wordpress.org/support/users/webtemyk/) * (@webtemyk) * [5 years, 9 months ago](https://wordpress.org/support/topic/code-not-working-logout/#post-13057829) * Nothing has changed in our plugin. Try creating a simple snippet with output to the screen. And check whether it works for unauthorized users? * Thread Starter [cristoto](https://wordpress.org/support/users/cristoto/) * (@cristoto) * [5 years, 9 months ago](https://wordpress.org/support/topic/code-not-working-logout/#post-13057850) * In my code some parts work fine. I did a echo after header function in my code, and I saw the result on the website correctly. But the header() function and setcookie aren’t working. * [Temyk](https://wordpress.org/support/users/webtemyk/) * (@webtemyk) * [5 years, 9 months ago](https://wordpress.org/support/topic/code-not-working-logout/#post-13058069) * These functions must be called before any output to the screen. You probably have something displayed on the screen before calling one of these functions. You can enable WordPress debugging mode and view PHP error logs * Thread Starter [cristoto](https://wordpress.org/support/users/cristoto/) * (@cristoto) * [5 years, 9 months ago](https://wordpress.org/support/topic/code-not-working-logout/#post-13058133) * I haven’t any code error. * The only change did it was update plugin. If it’s error code, the code not works with an authorized user too. * I activated the debug mode to show errors but wordpress doesn’t show any error in my code. It’s very strange. * I’m despereta with this problem, because our customers need it this sections to work. * You can check into the url: [https://atecresa.com/logincliente/](https://atecresa.com/logincliente/) User: [cristo@atecresa.com](https://wordpress.org/support/topic/code-not-working-logout/cristo@atecresa.com?output_format=md) Pass: ArPBtSJQaDdG * The php works because the api return ok, but some part of the code not work. - This reply was modified 5 years, 9 months ago by [cristoto](https://wordpress.org/support/users/cristoto/). * [Temyk](https://wordpress.org/support/users/webtemyk/) * (@webtemyk) * [5 years, 9 months ago](https://wordpress.org/support/topic/code-not-working-logout/#post-13058212) * Enable debug mode – add these lines to the **wp-config.php** file: * ``` define( 'WP_DEBUG', true ); define( 'WP_DEBUG_LOG', true ); define( 'WP_DEBUG_DISPLAY', false ); ``` * After that, try to login.
