I have the same problem on my host.
Configuration: WP: 4.3; WC: 2.1.13, SS: 1.3.2.
Environment variables:
* Imagick PHP Enabled
* Maximum Execution Time 600
* Memory Limit 256M
* Exec Commands Enabled
The “//public_html/ss_media/new” directory is empty.
Sometimes, after running the cronjob task, I’m getting the error message:
Fatal error: Call to undefined function finfo_open() in //public_html/wp-content/plugins/symbiostock/tools-ftp.php on line 114
