I use W3 total cache manual minify. Because it works perfectly on my blog. However, today after I added another 3 JS and two CSS files to W3TC minify URL, this plugin stopped minify my HTML, JS and CSS.
Then I wiped cache (empty all cache), nothing happened, Then I manually deleted /wp-content/cache/ folder, but nothing happens. I disabled and enabled HTML, JS and CSS minify. No luck. (I can only fix it delete plugin and delete remain w3tc files in wp-content folder. But it's not a good solution)
Still Google page speed insight display I have to minify my HTML, JS and CSS. Earlier it doesn't show that message.
So how do I fix this issue? Anybody has an idea?
