Hello @uts,
I am sorry about the issue you are having but I am happy to assist you with this.
W3 Total Cache does support Cloudfront and more.
It seems your plugin update/installation process failed to update files (You can update manually in that case)
If the issue still persists try to completly remove W3 Total Cache and re-install it:
1. Purge Cache
2. Deactivate and Delete Plugin
3. Check .htaccess File (make backup)
W3TC will create many directives in .htaccess file to control the caching behavior. Each section will start and end with comments like “#BEGIN W3TC Page Cache core” and “#END W3TC Page Cache core”.
Ensure that no residual entries are leftover in your .htaccess file after deleting the plugin.
4. Delete wp-content files and folders
– cache folder
– w3tc-config folder
– object-cache.php File (if exists)
– advanced-cache.php (if exists)
– dbcache.php (if exists)
– upgrade folder
– W3-total-cache folder in your /plugins/ folder (if exists)
5. Delete Cached Files from CDN (if using CDN)
Besides deleting all the relevant files, if you use CDN then ensure to purge the cached content from your CDN. This is necessary when you enabled minify option in W3TC settings. You should delete the minified and combined scripts and CSS files from your CDN server to avoid the site breaking on the browser.
6. Re-install W3 Total Cache
