Title: Plugin causes errors in WP Last modified: December 8, 2025 --- # Plugin causes errors in WP * Resolved [ammo69](https://wordpress.org/support/users/ammo69/) * (@ammo69) * [5 months, 3 weeks ago](https://wordpress.org/support/topic/plugin-causes-errors-in-wp-2/) * On WP version 6.8.3 / PHP 8.3 my site experienced problems with this plugin. type E_ERROR caused by line nr. 76 of the file wp-content/plugins/user-access- manager/src/Command/GroupCommand.php. Error: Uncaught Error: Cannot call constructor in wp-content/plugins/user-access-manager/src/Command/GroupCommand.php:76Stack trace:#0 wp-content/plugins/user-access-manager/init.php(258): UserAccessManager\ Command\GroupCommand->__construct()#1 wp-content/plugins/user-access-manager/ user-access-manager.php(77): initUserAccessManger()#2 wp-includes/class-wp-hook. php(341): initUam()#3 wp-includes/class-wp-hook.php(365): WP_Hook->apply_filters()# 4 wp-includes/plugin.php(522): WP_Hook->do_action()#5 wp-settings.php(742): do_action()# 6 wp-config.php(115): require_once(‘/home/xxxxxxxxxxx’) * Now I have WP 6.9, still the same error. It looks like the plugin does function but this is a bit weird. Are you [@gm_alex](https://wordpress.org/support/users/gm_alex/) still developing this (8 months ago latest update) or should I look for an alternative?

I uploaded the site error log to Gemini and this the conclusion:1. The Critical Issue: Conflict Between Plugins * The most recent and serious errors are caused by a conflict between two plugins:** User Access Manager** and **Asgaros Forum**. - **The Error Message:** `PHP Fatal error: Uncaught TypeError: UserAccessManager\ Object\ObjectHandler::registeredTaxonomy(): Argument #2 ($objectType) must be of type array|string, null given`. - **What is happening:** The plugin _Asgaros Forum_ attempts to register a taxonomy( a grouping, like categories). The _User Access Manager_ plugin monitors this process but receives an empty value (`null`) where it expects a string or list. Due to stricter rules in newer PHP versions (likely running PHP 8.0 or higher), this leads directly to a fatal crash. - **Consequence:** Your backend (wp-admin) is likely inaccessible or barely responsive. * **Solution:** You must disable one of these two plugins to regain access. Since you probably cannot enter the admin panel, this must be done via FTP or the File Manager of your hosting (DirectAdmin/cPanel). * Summary * Your site is crashing due to the **User Access Manager** plugin in combination with the forum. Disable User Access Manager manually via the files on the server to get the site working again. How to fix this?Best regards, AMMO * Plugin Author [gm_alex](https://wordpress.org/support/users/gm_alex/) * (@gm_alex) * [5 months, 2 weeks ago](https://wordpress.org/support/topic/plugin-causes-errors-in-wp-2/#post-18749001) * Hi, * new release is on the way and will be available within the next minutes.

A fix for me was modifying line 156 in /src/Controller/ Frontend/TermController.php and add “string” as a possible type for $term and the return value: *     private function processTerm(bool|WP_Term|**stdClass**|string $**term**, bool &$**isEmpty** = null): WP_Term|**stdClass**|bool|string * (sorry for hijacking the thread) * Plugin Author [gm_alex](https://wordpress.org/support/users/gm_alex/) * (@gm_alex) * [5 months, 2 weeks ago](https://wordpress.org/support/topic/plugin-causes-errors-in-wp-2/#post-18749167) * [@ammo69](https://wordpress.org/support/users/ammo69/) [@helmuthb](https://wordpress.org/support/users/helmuthb/) New release is on the way, please check it.
