This is a workaround for sites experiencing any issues with the ability introduced in WordPress 6.9 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>. The known issues have been fixed during the 7.0 release cycle with the following commits:
<ul>
<li><a href="https://core.trac.wordpress.org/changeset/61076" rel="nofollow ugc">r61076</a>: Script Loader: Fall back to hoisting late-printed styles to end of HEAD if wp-block-library is not enqueued.</li>
<li><a href="https://core.trac.wordpress.org/changeset/61122" rel="nofollow ugc">r61122</a>: Script Loader: Load block styles on demand in classic themes even when wp-block-styles support is absent.</li>
<li><a href="https://core.trac.wordpress.org/changeset/61174" rel="nofollow ugc">r61174</a>: Script Loader: Improve hoisted stylesheet ordering (in classic themes) to preserve CSS cascade.</li>
<li><a href="https://core.trac.wordpress.org/changeset/61554" rel="nofollow ugc">r61554</a>: Script Loader: Preserve original CSS cascade for classic themes when hoisting late-printed styles.</li>
<li><a href="https://core.trac.wordpress.org/changeset/61945" rel="nofollow ugc">r61945</a>: Script Loader: Refine hoisted stylesheet ordering to preserve original CSS cascade in classic themes.</li>
</ul>
If running a classic theme (i.e. not a block theme), this plugin 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 7.0. 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 should be 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. Nevertheless, as explained in the <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">dev note</a>, some sites may be built in a way that fundamentally does not work with loading separate block styles on demand. For these sites, this plugin is available to retain the old behavior.

Load Combined Core Block Assets

Workaround for sites experiencing issues with WordPress 6.9's changed default behavior to load block styles on demand in classic themes.

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.
