This is a temporary workaround for sites experiencing any issues with WordPress 6.9’s new ability to <a href="https://make.wordpress.org/core/2025/11/18/wordpress-6-9-frontend-performance-field-guide/#load-block-styles-on-demand-in-classic-themes" rel="nofollow ugc">load block styles on demand in classic themes</a>, for example <a href="https://core.trac.wordpress.org/ticket/64354" rel="nofollow ugc">#64354</a>.
If running a classic theme (i.e. not a block theme), it filters <code>should_load_separate_core_block_assets</code> to be <code>false</code>. This has the effect of reverting a change introduced in 6.9 where classic themes now load separate core block assets on demand by default.
Note that this plugin should be considered temporary until any issues are resolved in 6.9.1. At any time, you can test whether any issues remain by adding <code>?should_load_separate_core_block_assets=true</code> to any frontend URL; this restores the default behavior in WP 6.9.
This workaround is temporary because there are performance benefits to loading separate core block assets. They can be loaded on demand just when they are used, as opposed to loading the large single combined <code>wp-block-library</code> stylesheet. Loading separate block styles on demand reduces the amount of CSS which should improve page load time.

Breeze Cache

2 updates since 2.0.10 have introduced bugs into my website, where previously it was working correctly with Breeze.

This has caused lots of lost time and some lost revenue.

I can't take the risk to run into more issues.

Quality control needs to improve. Something is going very wrong there.

Will update this review if anything changes, but this is the truth for now.

Keep running into problems


Hey, for quick and effective page caching, go for this plugin – it's great with or without Varnish or Cloudflare CDN. No need to mess around with CSS and JS; there's another plugin for that, doing the fancy stuff. Stick to this one for caching, and let the other one handle the techy bits. Easy peasy!


I suggest using it for Page Caching only, not CSS & JS optimization


Not bad, but you have to add the next features, without it, it's just another cache plugin.




Remove unused css!!!



Better support to CDN with exclude / include custom directory and files



And maybe, checking the plugin performance when the minify option is enabled.




Thanks


Not bad... But you have a work to do.

Breeze is a caching plugin developed by Cloudways. Breeze uses advance caching systems to improve site loading times exponentially.
