 * Did the plugin is adding `define( 'WP_CACHE', true ) ;` to the wp-config.php 
   file?
    Can I remove it?

 * No, the EWWW Image Optimizer does not add that to your wp-config.php. It’s usually
   added by page caching plugins. If you have a page caching plugin, you should 
   definitely NOT remove it.
 * If you have server-based caching, then you can probably remove it, but I’d double-
   check with your web host.
 * If you have neither, then you should go get a page caching plugin to speed up
   your site. I recommend WP Super Cache or Cache Enabler.

 * Great, thanks
    I think I had caching plugin but I remove it because it didn’t
   help. So the plugin didn’t clean all it settings are I delete it
