[Plugin: User Access Manager] ERROR in useraccessmanager.class.php Line 1881

wp user control and other rights-managing plugins cause an error at line 1881 in the class-file “UserAccessManager.class.php”

don’t know why.. but as soon as one of these plugins are activated, wp crashes and you have to reset the plugins via phpmyadmin. (wp_options -> active_plugins -> delete the contents)
