I successfully was able to smush 7100 out of 8800 images and it took way longer because I received over a 1100 errors like the screenshot above to the point where it stopped several times and gave me the same msgs. like above but in addition had a red rectangle box that said I need to contact support so you guys can fix the issues.
I successfully smushed and super smushed 180MB and my site is loading faster now, the Hummingbird in which I have another ticket created keeping it separate as you requested has helped out greatly this go around with minimum issues with the plugin. This ticket is for wpSmush Pro.
James - BTW I have extended the login to admin for support another 5 days for you guys. - I am starting to like being a part of the WPDEV Community and learning my way through your plugins and talking to the community. God Bless.
