AccelerateWP is a CloudLinux feature that adds a WordPress optimisation suite to cPanel. It can enable page caching and related optimisations for a WordPress site in one click, and its smart advice can suggest fixes based on how a site actually performs. Availability depends on how the server is licensed and configured.
Before you start
- A WordPress site on a CloudLinux server.
- Check whether AccelerateWP appears in your cPanel (often under Software). If it does not, it is not enabled for your account.
What it does
- Optimisation suite: installs and configures a caching and optimisation plugin for the site with sensible defaults.
- Smart advice: CloudLinux analyses slow sites (using data similar to X-Ray) and recommends specific actions, such as enabling an object cache or fixing a slow plugin (see CloudLinux X-Ray).
- Premium features on some servers: object caching and CDN integration, which may be paid add-ons.
Turn it on for a site
- Open AccelerateWP in cPanel.
- Find your WordPress site in the list.
- Enable the optimisation suite for that site.
- Test the site in a private window and check key pages and forms.
AccelerateWP or LiteSpeed Cache?
| LiteSpeed Cache | AccelerateWP | |
|---|---|---|
| Cache engine | LiteSpeed server-level cache | Depends on server setup |
| Best on | LiteSpeed servers, such as MdmHost | CloudLinux servers, especially without LiteSpeed |
| Control | Very detailed settings | Simple, one-click defaults and advice |
On MdmHost's LiteSpeed servers, LiteSpeed Cache is the recommended caching plugin (see configuring LiteSpeed Cache).
Warning: Do not run two page-caching plugins on one site. If you enable AccelerateWP's suite, disable other cache plugins, and the other way round.
Using smart advice
If AccelerateWP shows advice for your site, read what it found and the suggested action. Apply one change at a time and measure the result with PageSpeed Insights or Resource Usage (see Resource Usage).
Turning it off
Disable the suite for the site in AccelerateWP. The plugin it installed is deactivated; purge any caches and test.
Frequently asked questions
Is AccelerateWP available on MdmHost?
Availability depends on server configuration. LiteSpeed Cache is available everywhere on MdmHost and is the recommended choice.
Does AccelerateWP work with WooCommerce?
Its suite excludes cart and checkout like other cache plugins, but test shops carefully after enabling.
Is smart advice automatic?
Advice appears when CloudLinux detects issues; applying it is a user decision, and some fixes are applied with a click.
Can I use AccelerateWP and LiteSpeed Cache image optimisation together?
Avoid overlapping features. Pick one plugin for caching and optimisation so settings do not conflict.
Will AccelerateWP change my theme?
No. It adds caching and optimisation; your theme and content stay the same. Optimisation options can affect layout, so test after enabling.
What should I do if my site breaks after enabling?
Disable the suite for the site in AccelerateWP, purge caches and check the site again, then re-enable features one at a time.
Who sees the smart advice?
Advice is shown to the account owner in cPanel; resellers can see it by opening the customer's cPanel from WHM.
