Yes, it works. Don’t worry. You can check the following image.

Emre, I use Cloudflare and I don’t see that comment in the bottom of pages. I think that Cloudflare strips out comments from pages — this might depend on particular Cloudflare settings. However, I can see that the cache files are being created, and in pages source I see links to css & js with “wpfc-minified” in the path.
I am assuming that the the wpfc-minified links exist only on cached pages and have verified that those links don’t show up on pages I have excluded from caching.
I’m just offering this so that you know that some of your users may not see the comment inserted at the bottom of the page in their browser because of the action of another program or plugin.
(I also know because it seems like all my pages started loading about 10 times as fast as soon as installed and activate the plugin .. but I understand the impulse to try to verify via page source).
you are right @abigailm 🙂 thank you.
