Hello,
I followed your instructions
-turned off my CDN while editing
-purged caches from all plugins (Auto-Optimize and W3 Total Cache)
It didn’t work.
I then downgraded the plugin to version 3.2.5 and it did’t work. I then put the plugin back to the most recent version.
Finally went into my chrome browser > clear browser data > clear cached images and files. This finally did the trick.
I appreciate your help in trouble shooting this problem.
Thanks and please close the ticket.
