Cache Enabler is a simple, yet powerful WordPress caching plugin that is easy to use, needs minimal configuration, and best of all helps improve site performance for a faster load time. It creates static HTML files of frontend pages and stores them on the server’s disk. This allows the static HTML files to be delivered instead of generating pages on the fly, avoiding resource intensive backend processes from the WordPress core, plugins, and database.

</ul>
<h4>How does the caching work?</h4>
Cache Enabler captures page contents and saves it as a static HTML file on the server’s disk. The static HTML file created can be one of several possible cache versions depending on the plugin settings and HTTP request. Accepted static HTML files are then delivered without any database queries or on the fly compression, allowing for a quicker page load.

WPO Tweaks is the most complete performance optimization plugin for WordPress. It combines the best WPO (Web Performance Optimization) practices in a single easy-to-use tool. No configuration needed: activate and enjoy a faster WordPress.
By default, WordPress loads several functions, services and scripts that are not mandatory and usually slow down your installation and consume hosting resources. For years I have been testing tweaks to save hosting resources and improve WordPress performance and loading times. After thousands of tests, this plugin includes my best speed and performance optimizations with a single click.
With this plugin you can safely disable those annoying services, unnecessary codes and scripts to save resources and hosting costs, and speed up WordPress to get better results in tools like Google PageSpeed, Pingdom Tools, GTMetrix, WebPageTest and others.

<h3>HOW TO VERIFY OPTIMIZATIONS ARE WORKING</h3>
You can check each optimization individually to ensure WPO Tweaks is working correctly:
Missing Image Dimensions: Inspect images in your browser (F12 > Elements). Images should have <code>width="X"</code> and <code>height="Y"</code> attributes even if they weren’t originally coded with dimensions.
Critical CSS: View page source (Ctrl+U) and look for <code><style id="ayudawp-wpotweaks-critical-css"></code> in the head section containing basic CSS rules.
Deferred CSS: In source code, look for <code><link></code> tags with <code>rel="preload" as="style"</code> instead of <code>rel="stylesheet"</code>, followed by <code><noscript></code> fallbacks.
Google Fonts Optimization: Google Fonts URLs should include <code>&display=swap</code> parameter.
Preconnect: Look for <code><link rel="preconnect"></code> tags in the head pointing to fonts.googleapis.com, fonts.gstatic.com, etc.
DNS Prefetch: Check for <code><link rel="dns-prefetch"></code> tags pointing to external domains like gravatar.com, stats.wp.com.
Lazy Loading: Inspect images (F12) – they should have <code>loading="lazy"</code> and <code>decoding="async"</code> attributes.
Resource Preload: Look for <code><link rel="preload"></code> tags for your theme’s CSS and critical fonts.
Version Removal: Source code should NOT contain <code><meta name="generator" content="WordPress X.X"></code> or <code>?ver=</code> in script/style URLs.
Dashicons Removal: When logged out, source code should NOT include <code>dashicons.min.css</code>. When logged in, it should appear.
Emojis Removal: Source code should NOT contain <code>wp-emoji-release.min.js</code> or emoji-related styles.
Header Cleanup: Source code should NOT contain <code><link rel="EditURI"></code>, <code><link rel="wlwmanifest"></code>, or <code><link rel="shortlink"></code>.
JavaScript Defer: Most <code><script></code> tags (except jQuery) should include the <code>defer</code> attribute.
GZIP Compression: Test at <a href="https://www.giftofspeed.com/gzip-test/" rel="nofollow ugc">giftofspeed.com/gzip-test</a> – should show “GZIP is enabled”.
Cache Headers: Check your <code>.htaccess</code> file for a section marked “BEGIN WPO Tweaks by Fernando Tellado” with expiration rules.
Heartbeat Control: In WordPress Dashboard, open browser dev tools (F12) > Network tab. AJAX requests to <code>admin-ajax.php</code> with <code>action=heartbeat</code> should occur every 60 seconds instead of 15.
Use tools like Google PageSpeed, GTMetrix, Pingdom Tools, and WebPageTest to measure overall performance improvements. Always test twice to account for caching effects.
<h3>COMPATIBILITY AND EXTENSIBILITY</h3>

<h3>MEASURING RESULTS</h3>
Recommended tools: 
* <a href="https://pagespeed.web.dev/" rel="nofollow ugc">Google PageSpeed Insights</a> 
* <a href="https://gtmetrix.com/" rel="nofollow ugc">GTMetrix</a> 
* <a href="https://www.webpagetest.org/" rel="nofollow ugc">WebPageTest</a>
Best measurement practices: 
* Run at least 2 tests (first one may not show cache) 
* Always use the same tool for comparison 
* Measure performance over time, not just once 
* Remember that no tool can replace human perception
