We just downloaded and installed Snapshot on our client's site. I tried to run a simple test backup to DropBox and received the following error.
ERROR: zip archive add failed [Array ( [type] => 2048 [message] => is_a(): Deprecated. Please use the instanceof operator [file] => /var/www/vhosts/fitchronaems.com/httpdocs/fitchronaems/wp-admin/includes/screen.php [line] => 376 ) ]
This sounds like it's out of my hands. Is this something you can help resolve? Thanks!
