 * This may be a WP glitch, but on the recent update it said Update failed – could
   not delete old version of plugin. Couldn’t reinstall it b/c the destination folder
   still exists – which only includes a debug file.
 * I’m using Autoptimize, if it helps – no image optimization is enabled. After 
   the failure I got AO’s message – Did you know Autoptimize includes on-the-fly
   image optimization…
 * Is there a conflict between EWWW and AO?

 * Also, is there anything I need to delete before reinstalling besides the plugin
   folder?

 * It’s just a glitch that happens sometimes when updating plugins. It’s possible,
   based on your description, that it only happens when debugging is enabled, as
   there have been a few folks who reported similar issues this release cycle, but
   I’ve not been able to reproduce it.
 * At any rate, you just have to delete the plugin folder, and you should be good
   to go.
 * As for EWWW IO and AO, the two work fine together, even with the on-the-fly image
   optimization, which is actually powered by ShortPixel.
 * We have a similar module/feature called ExactDN, which does on-the-fly image 
   optimization, image scaling/resizing, lazy loading, and more. You can read about
   it at [https://ewww.io/resize/](https://ewww.io/resize/)
 * The way the “on-the-fly” modules work is that they copy your images to a CDN 
   system, where they are optimized, and passed on to your visitors. It’s the easiest
   and fastest way to improve image performance, BUT it leaves your original images
   untouched on the server (including all the WP-generated thumbnails).
 * For some folks, that’s great, as it’s a zero-risk solution for image optimization.
   But many folks also want to compress the originals on the server, to save on 
   disk space usually. In that case, you need a plugin that will take care of that
   side of things too. EWWW IO does both modes, or if you want to try the free “
   on-the-fly” module from AO, you can do that too.

 * Thanks – reinstalled and everything works.

 * So theoretically image optimization could be handled by EWWW and CDN by ShortPixel?

 * Yes, you can use the ShortPixel CDN alongside EWWW IO. So for the CDN portion,
   you can use our ExactDN, ShortPixel Adaptive Images, or the AO image optimization(
   only the latter is completely free).

 * Cool – thanks for the help. The site is running faster without using Shortpixel’s
   CDN, go figure.
 * What’s the js used for JS WebP Rewriting, in case I need to exclude it in AO 
   if there are any issues? I can’t seem to find it in page source.

 * It’s inlined, so you shouldn’t ever have to exclude it from AO. The plugin does
   it inline so that the images start loading faster, rather than waiting for an
   extra JS request.
    If you search for ewww_webp, you should find the script block
   in the page source.
