Solid Performance 1.4.0 Released: Caching & Preloading Enhancements, Plus a Critical Bug Fix
Solid Performance 1.4.0 introduces powerful caching and preloading enhancements, including sitemap-based preloading, WP CLI commands, and improved debugging. This update also fixes a critical configuration issue, ensuring seamless access to settings.

SolidWP has just released Solid Performance 1.4.0, bringing powerful enhancements to caching and preloading while addressing a critical bug. This update is designed to improve website speed, optimize cache handling, and ensure a smoother experience for site administrators. Let’s dive into the key improvements and what they mean for your WordPress site.
Enhancements in Solid Performance 1.4.0
1. Sitemap-Based Preloading
One of the standout features of this release is the ability to preload cache based on sitemap URLs. This means Solid Performance can now intelligently cache your site’s most important pages by pulling them directly from your sitemap, ensuring that high-traffic and crucial content loads as quickly as possible.
2. New WP CLI Commands for Preloading
For users who prefer command-line management, Solid Performance 1.4.0 introduces new WP CLI commands:
wp solid perf preload status– Check the status of the current preloading process.wp solid perf preload start– Initiate a manual preloading process.wp solid perf preload cancel– Halt an ongoing preloading task.
These commands provide greater flexibility and control over cache management, making it easier for developers and administrators to optimize site performance efficiently.
3. Improved Admin Bar Cache Purging
Previously, purging a single URL from the WordPress Admin Bar would only remove the cache. Now, with this update, purging a URL will also trigger automatic preloading, ensuring that the purged page is immediately re-cached for optimal performance.
4. Enhanced Cache Handling: PHP Headers Support
Cache files in Solid Performance 1.4.0 now capture and serve PHP-set headers. This improvement allows for better compatibility with various server configurations and ensures that necessary headers are preserved when serving cached content.
5. Verbose Logging for Debugging
Troubleshooting and performance monitoring get a boost with new verbose logging when WP_DEBUG is set to true. Developers can now fine-tune log levels using the solidwp/performance/log/level filter by specifying one of the following log levels:
- debug
- info
- notice
- warning
- error
- critical
- alert
- emergency
This level of control ensures that administrators can capture relevant logs without unnecessary noise, making debugging more efficient.
Critical Bug Fix: Configuration Settings Issue Resolved
In previous versions, invalid configuration values could sometimes prevent access to the settings page, making it difficult for users to adjust performance settings. Solid Performance 1.4.0 resolves this issue, ensuring that users can always access and modify settings without disruption.
Why Update to Solid Performance 1.4.0?
This update is essential for anyone looking to enhance website speed, streamline caching, and ensure stability in their WordPress performance optimization setup. With sitemap-based preloading, enhanced cache handling, better WP CLI integration, and improved debugging tools, Solid Performance 1.4.0 is a must-have for WordPress users serious about site performance.
