HTML, CSS & JS optimization plugin for developers and advanced users. Note you need to look into the HELP tab after installing the plugin and manually configure it for your site. Each site is different, so the default recommendations may or may not work for you and you will need to test and find out how to adjust your settings.
Minification is done on the frontend during the first uncached request. Once the first request is processed, any other pages that require the same set of CSS and JS files will be able to reuse the same generated static CSS or JS file.
If your cache is growing significantly, this could mean one of your CSS or JS files is dynamic and changes on every pageview. In that case, you would need to add the file to the ignore list, else the cache would grow indefinitely…
I’ve been using this plugin for a long time now and it meets my needs for Simplicity and Effectiveness totally.
The plugin support is also very fast and efficient, and again, all in terms I can understand.
I’d recommend this plugin to anyone totally and unreservedly!
Great plugin to compress and cache html/js/css easily
Tried them all. The results, simplicity and unobtrusiveness of this plugin makes it the winner. Thank you!
Plugin has got compatibility issues with PHP 8.1
Issue: ICONS break on the website and is replaced with some weird characters.
Example Icons: Basket ICON / Down arrow / Wish list Heart Icon etc.
Issue is after upgrading PHP from 8.0 to 8.1 (stable release).
If plugin is deactivated with PHP 8.1 icons return to their normal view. Enable it and converts icons to weird characters again.
Reverted back PHP to 8.0 and it works perfectly fine.
Can this be fixed as in order to stay inline with the latest stable PHP releases, please?
