“We need FTP access details to apply a fix or you can try to update wp-config.php manually with new keys which can be generated here: https://api.wordpress.org/secret-key/1.1/salt/
After updating the keys if the plugin activation does not work we will need to log in to wp-admin or via FTP again and drop it manually.”
We remain at your service.
