);Hello Adam,
Thank you for reaching out and I am happy to assist you with this.
Can you please share the screenshot of the W3 Total Cache settings in Performance>Minify> JS section and please let me know if you had the YUI Compressor enabled before or have you just selected this option and the issue started to occur?
Thanks!Hello,
I just tried to enable it. So, I installed Java and YUICompressor and tried to anable it in W3 Total Cache.
Can not attach screenshot – so I am writing settingJS minify settings: Enable
Minify method: Combine & Minify
Minify engine settings:
Operations in areas:
Before </head>
After <body>
Preserved comment removal (not applied when combine only is active)
Line break removal (not safe, not applied when combine only is active)
HTTP/2 push EnableHello Adam,
YOu can upload the images to imgur.com and share the link.
Thank you for the feedback.
Can you please also share what you added to the Path to JAVA executable: and Path to JAR file: and what message you are getting when clicking the Test YUI Compressor button?
Thanks!Hello,
I am sending you pictures of minify and browser cache.

content-encoding: brHello Adam,
Thank you for your feedback.
We need to replicate this and make sure that the paths are correct and the Java is installed correctly
I’ll get back to you once I have more details and am able to replicate the problem.
FOr the time being, you should use the default Minify option.
As for the Brotli, W3 Total Cache only recognizes the PHP extensions so please make sure that the https://github.com/kjdev/php-ext-brotli PHP brotli extension is installed on your server.Thanks!
https://github.com/kjdev/php-ext-brotli is installed
#php -modules
[PHP Modules]
brotli
calendar

curl
…Hello,

Adam WolakHello,
