 * Hi [@ealbertini](https://wordpress.org/support/users/ealbertini/) ,
 * Thanks for reaching out.
    It seems that the error was from using old version 
   of WordPress. Is it correct? And please let me know if you are using the Free
   or Pro Version.
 * Best regards,
    Kelly

 * Hi Kelly – I’m running WP 4.6.14 and it was the free version. I was able to release
   the site by disabling the plugin via FTP.

 * Hi [@ealbertini](https://wordpress.org/support/users/ealbertini/) ,
 * The FileBird current version supports WordPress Version 4.7 or greater. We will
   update the new version which also supports WordPress Version 4.6.xx or older 
   soon. Please stay tuned.
 * Best regards,
    Kelly
