Some files were not in sync in the repository, and that was part of the problem.Please report if it works.Regards, Chris * Plugin Author [docjojo](https://wordpress.org/support/users/docjojo/) * (@docjojo) * [2 years ago](https://wordpress.org/support/topic/atec_nonce-undefined-function/#post-17763917) * Hello, sorry for the inconvenience.Please install the new version 1.4.6.Regards, Chris. * Thread Starter [eragonsoftware](https://wordpress.org/support/users/eragonsoftware/) * (@eragonsoftware) * [2 years ago](https://wordpress.org/support/topic/atec_nonce-undefined-function/#post-17764656) * Good to see you care about the plugin and tried to update it. I have followed your instruction, but unfortunately it cannot be activated, upon activation, it triggers a fatal error. * “Plugin could not be activated because it triggered a **fatal error**.” That’s the notification that appears with red, from the plugins screen and it cannot be activated. If I try activating right from the plugin installation screen, a slightly different error showsActivation failed: error * Plugin Author [docjojo](https://wordpress.org/support/users/docjojo/) * (@docjojo) * [2 years ago](https://wordpress.org/support/topic/atec_nonce-undefined-function/#post-17764670) * You can also send me a [https://wordpress.org/plugins/temporary-login-without-password/](https://wordpress.org/plugins/temporary-login-without-password/) but to be save we should also have an FTP fallback.Do you have FTP access? * Plugin Author [docjojo](https://wordpress.org/support/users/docjojo/) * (@docjojo) * [2 years ago](https://wordpress.org/support/topic/atec_nonce-undefined-function/#post-17764719) * can you set `define('WP_DEBUG', true);``define('WP_DEBUG_LOG', true);`in wp-config. phpand then send wp-conent/debug.logafter v1.4.7 activation? * Plugin Author [docjojo](https://wordpress.org/support/users/docjojo/) * (@docjojo) * [2 years ago](https://wordpress.org/support/topic/atec_nonce-undefined-function/#post-17777110) * v1.5.1 is online, please deactivate the old version, delete the plugin and install the new version 1.5.1. * Thread Starter [eragonsoftware](https://wordpress.org/support/users/eragonsoftware/) * (@eragonsoftware) * [2 years ago](https://wordpress.org/support/topic/atec_nonce-undefined-function/#post-17777251) * I believe this is what is of interest to you, mate, this is why your plugin is generating fatal errors: if a site also has atec cache info installed, that one already has a function with the same name as the one in atec cache acpu, that’s why atec cache cannot be activated. * Have a look at this: [23-May-2024 20:14:05 UTC] PHP Fatal error: Cannot redeclare atec_plugin_settings() (previously declared in /…/public_html/wp-content/plugins/ atec-cache-info/includes/atec-tools.php:9) in /…/public_html/wp-content/plugins/ atec-cache-apcu/includes/atec-admin.php on line 5Use another name or if it’s the same function , use if(!function_exists(‘atec_plugin_settings’)) … though I doubt this would be a good case, since in each plugin we are talking about different settings. * I hope this helps. - This reply was modified 2 years ago by [eragonsoftware](https://wordpress.org/support/users/eragonsoftware/). * Plugin Author [docjojo](https://wordpress.org/support/users/docjojo/) * (@docjojo) * [2 years ago](https://wordpress.org/support/topic/atec_nonce-undefined-function/#post-17777267) * Hi, function atec_plugin_settings was moved to atec-admin.php and there is a ` if (!defined('ATEC_ADMIN_INC')) require_once(**DIR**.'/includes/atec-admin.php');` in the plugin file to prevent that kind of conflict.But you probably have unmatching versions of my plugins installed.Please update to the latest version. * apcu v1.5.1 cache 1.4.6 That should solve the problem.Thank you. * Thread Starter [eragonsoftware](https://wordpress.org/support/users/eragonsoftware/) * (@eragonsoftware) * [2 years ago](https://wordpress.org/support/topic/atec_nonce-undefined-function/#post-17778101) * atec cache info is 1.3.9, there is no update available from wordpress.org * the apcu I installed yesterday, was indeed, 1.5.1 Since there was no update available, I presumed there’s no newer version online. Now I have deleted both, (apcu cache and cache info), and installed them, and now they work together, no error is generated, however, the object-cache.php can only be generated if I turn off all other caching plugins, like Litespeed. * Thank you for all your effort and keep up the good work. Wish you all the best! * Plugin Author [docjojo](https://wordpress.org/support/users/docjojo/) * (@docjojo) * [2 years ago](https://wordpress.org/support/topic/atec_nonce-undefined-function/#post-17778150) * you can run APCu cache with litespeed cache plugin but need to disable object cache (memcached / redis) in litespeed, as they both engage with WP Object Cache. So you can only use either one being active. if you have litespeed cache running on a litespeed server with redis (:6378) i recommend using this combination and not add apcu cache. I asume you are runing LSWS? * Plugin Author [docjojo](https://wordpress.org/support/users/docjojo/) * (@docjojo) * [2 years ago](https://wordpress.org/support/topic/atec_nonce-undefined-function/page/2/#post-17778320) * LSWS has it’s own object-cache.php and atec APCu cache checks for the existence of this file and will not overwrite but give a warning: * ```wp-block-code $debug='ERROR:Another "object-cache.php" file already exists.'; ``` Viewing 12 replies - 1 through 12 (of 12 total) The topic ‘atec_nonce() UNDEFINED FUNCTION’ is closed to new replies. * ![](https://ps.w.org/atec-cache-apcu/assets/icon.svg?rev=2926115) * [atec Cache APCu](https://wordpress.org/plugins/atec-cache-apcu/) * [Frequently Asked Questions](https://wordpress.org/plugins/atec-cache-apcu/#faq) * [Support Threads](https://wordpress.org/support/plugin/atec-cache-apcu/) * [Active Topics](https://wordpress.org/support/plugin/atec-cache-apcu/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/atec-cache-apcu/unresolved/) * [Reviews](https://wordpress.org/support/plugin/atec-cache-apcu/reviews/) * 17 replies * 2 participants * Last reply from: [docjojo](https://wordpress.org/support/users/docjojo/) * Last activity: [2 years ago](https://wordpress.org/support/topic/atec_nonce-undefined-function/page/2/#post-17778320) * Status: resolved
