I have JS/CSS/HTML minification enabled on my Cloudflare dashboard. HOWEVER the HTML files are not being minified (if I have inline CSS/JS they are not being minified and not even the HTML code itself is being minified).
The CSS/JSS are being minified perfectly. I have no pagerules running and nothing crazy that could prevent this from working.
So it looks like a bug cause. I have HTML minify enabled (check print attached).
Also, try to access https://www.sitepor500.com.br/ in your browser. You will see a HIT in the CF cache but the inline CSS/JS code is not being minified inside the HTML code.
