AccelerateWP

AccelerateWP is a free WordPress performance suite included with Ultra Web Hosting. It bundles object cache, full-page cache, CSS/JS optimization, lazy-loaded images, and an optional CDN. Most sites see page-load time drop by 40 to 70 percent after enabling it, with no theme or plugin changes required.

What's Inside

AccelerateWP is a CloudLinux product wired into your cPanel. It activates several optimizations together:

• Object Cache (Redis or Memcached) — WordPress repeatedly asks the database the same questions ("what is the site title?"). Object cache stores those answers in memory so the database is asked once, not on every page load.
• Full-Page Cache — Saves the rendered HTML of each page so subsequent visitors get it without WordPress running at all. Drops time-to-first-byte dramatically.
• CSS & JS Optimization — Minifies, combines, and defers stylesheets and scripts so the browser parses less code on each page.
• Image Optimization — Lazy-loads images below the fold and serves them as WebP when the visitor's browser supports it.
• CDN (optional) — Serves static assets from a global edge network so visitors far from our server still get fast loads.

Enabling AccelerateWP on a Site

1. Log into cPanel.
2. Under Software, click AccelerateWP.
3. You will see a list of WordPress installations cPanel has detected on your account. If your site is missing, click Scan to find it.
4. For the site you want to accelerate, click Enable in the Smart Advice column. AccelerateWP will recommend a set of optimizations.
5. Click Apply to turn them on. The page reloads with each optimization marked active.

Verifying It's Working

1. Open your site in a private/incognito browser window (so you bypass logged-in admin bypass rules).
2. Load the home page once and then reload it.
3. Right-click → View Page Source and search for the marker Page generated by or look for a comment near the end of the HTML. Cached pages will identify themselves.
4. Run a speed test at PageSpeed Insights or WebPageTest. Compare before-and-after numbers.

Individual Features

Object Cache

Best for: any WordPress site, especially WooCommerce, membership sites, BuddyPress, and dashboards with many widgets. Object cache is the single biggest lever for sites that are slow because of database queries.

If your site uses an external object-cache plugin (W3 Total Cache, LiteSpeed Cache, etc.), AccelerateWP will warn you about a conflict. Pick one. AccelerateWP's object cache is generally simpler and managed for you.

Full-Page Cache

Best for: blogs, marketing sites, brochure sites, news, anything where the same page is shown to many visitors.

Skip or carefully tune for: WooCommerce carts and checkouts, membership-restricted pages, dynamic dashboards. AccelerateWP automatically excludes cart and checkout pages on detected WooCommerce sites; verify the exclusion list under the cache settings.

CSS & JS Optimization

Best for: most themes and page builders. Reduces the size and number of requests the browser makes.

Watch for: visual breakage with heavily customized themes. If menus stop working or a layout breaks after enabling JS combine, turn that one option off (leave minify on) and re-test.

Image Optimization

Best for: image-heavy sites (photographers, product catalogs, blogs with hero images). Lazy-loading defers off-screen images until the visitor scrolls; WebP conversion reduces image size by 25 to 50 percent versus JPEG/PNG.

Common Issues

• "My changes do not show up after editing a page." — The full-page cache is serving the old version. Clear the cache: in cPanel → AccelerateWP, click Purge Cache for the affected site. Or log into WordPress as admin; the cache normally bypasses for logged-in users so you can verify the edit.
• "My site broke after enabling JS optimization." — A plugin or theme script does not tolerate being combined or deferred. Disable JS combine first; if the issue persists, disable JS defer; if still broken, disable JS minify. Most issues clear after disabling combine alone.
• "WooCommerce checkout shows the wrong cart." — A cache rule is too aggressive. Confirm cart/checkout pages are in the exclusion list. If they are and it still happens, open a support ticket.
• "PageSpeed score did not improve." — Test the home page in incognito after a few loads. The first load after enabling caches is slower because caches are cold. If scores still do not improve, the bottleneck may be a heavy theme or page builder rather than something cache can fix.

Disabling AccelerateWP

If you need to temporarily turn off AccelerateWP for troubleshooting:

1. In cPanel → AccelerateWP, find the site.
2. Toggle off individual features, or click Disable to turn everything off.
3. The site reverts to standard performance behavior immediately.
