 * Hi [@iamkingsleyf](https://wordpress.org/support/users/iamkingsleyf/),
 * Seams like two possible thing happened. Either you manually (via FTP) uploaded
   AAM to your server and it did not override some of the core AAM files or some
   of the core AAM files have permissions setup is such a way that PHP executable
   can’t delete them.
 * Try to completely delete wp-content/plugins/advanced-access-manager folder and
   reinstall AAM from the official WordPress repository. This will definitely solve
   your problems.
 * Keep me updated.
 * Regards,
    Vasyl

 * [@iamkingsleyf](https://wordpress.org/support/users/iamkingsleyf/),
 * Please follow the instructions I’ve mentioned earlier. This error is not possible
   if plugin is installed correctly.
 * Remove the entire folder physically and reinstall plugin.
 * Regards,
    Vasyl
