 * Hi [@realpascal](https://wordpress.org/support/users/realpascal/)!
 * This problem can happen, when the server didn’t moved the files correctly during
   update. You should follow this documentation:
    [https://smartslider3.helpscoutdocs.com/article/418-wordpress-alternative-update#ftp](https://smartslider3.helpscoutdocs.com/article/418-wordpress-alternative-update#ftp)
   so delete your current Smart Slider 3 and install it through ftp instead to make
   sure all files are there. Don’t worry, your sliders will stay!
 * And please try to use our latest build instead, which isn’t public yet, but it
   has a lot of fixes:

 * If there still would be something wrong after that, please write to me to [support@nextendweb.com](https://wordpress.org/support/topic/fatal-error-cannot-declare-class-n2pluggable/support@nextendweb.com?output_format=md)
