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?
