 * Hey [@kreativesk](https://wordpress.org/support/users/kreativesk/)
 * Thanks for the feedback! That function looks like a core WP function. [https://developer.wordpress.org/reference/functions/plugin_dir_path/](https://developer.wordpress.org/reference/functions/plugin_dir_path/)
   
   Its possible the archive may have not extracted properly or the package file 
   was not properly created. You might try and run the installer again or even try
   and build a new package.
 * If that does not help and you want to submit a [support ticket](https://snapcreek.com/ticket)
   for this issue we can have a closer look at your setup. Please provide a link
   to this thread when submitting the ticket.
 * Cheers~
