Aha, that shows something interesting. The images in your slider are all 1400×500 versions of the images, but in the debug log there is no reference to that size/version of the image, nor any indication that it is a size “registered” via the normal WordPress methods.
I suspect those images have likely not been optimized at all, since they are essentially “unregistered sizes” and would require configuring EWWW IO to do a more low-level folder scan of the uploads folder.
You can read more in our docs at https://docs.ewww.io/article/4-getting-started (Beyond the Media Library section) but let’s start with this:
1. Enable “Ludicrous Mode”
2. On the Advanced tab, add this folder into Folders to Optimize: /home/customer/www/staging3.canyoncatering.net/public_html/wp-content/uploads/2015/
3. Run a bulk optimize, shouldn’t need to check any boxes for this.
During the bulk optimizer, the plugin will then scan the 2015 folder on the server directly. Assuming those unregistered sizes have never been optimized by EWWW IO, it will then optimize the images and convert them to WebP.
IF they have somehow been processed by EWWW IO before, then just use the Force re-opt and WebP Only options and try it again.
Once you’ve confirmed it working for the 2015 folder, go ahead and change the Folders to Optimize to this:
/home/customer/www/staging3.canyoncatering.net/public_html/wp-content/uploads/
And then run the bulk again to process the unregistered sizes for all your images.
Afterwards, you might need to enable the Include Media Folders and Scheduled Optimization to process the unregistered sizes for new uploads. Remove the uploads folder from the Folders to Optimize though, that way the scheduled job only needs to scan a couple folders at a time instead of the entire /uploads/ folder.
