 * Hello [@animerd](https://wordpress.org/support/users/animerd/),
 * Hope you’re doing well!
 * The debug.log showing that there are missing files `..No such file or directory
   in ..`. Please re-install the plugin to fix this issue.
 * You can upload the plugin via FTP, to the `/wp-content/plugins/` directory by
   replacing current `/wp-hummingbird/` folder.
 * Let us know how it went!
 * Kind regards,
    Nastia

   Feel free to post back any updates though, and we can re-open it and continue
   troubleshooting. 🙂
