Activate Plugin Fatal Error

Hi –
We are getting a fatal error when trying to activate the plugin.

The server we are currently uses the SSH SFTP Updater Support plugin to allow plugins to be installed.
This plugin was already active when we migrated and was running fine but needed to be deactivated temporarily – and now does not activate.

Can you please help advise how we can get your awesome plugin working again?
