WebFacing – Disk Usage from cPanel® on Dashboard & in Site Health


🕸️ By WebFacing. Shows disk usage information, recommendations and alerts, plus number of email accounts,
in your admin Dashboard At a Glance widget and on Site Health panels.
Includes an email routing test (when server is not authority, routing must be remote).
Also includes a Site Health test for HTTPS only
(http should not be allowed, but forwarded to https) with information about the issue, recommendation and actions.
Made with a little help from cPanel, L.L.C., USA and PRO ISP AS, Norway – many thanks.

This plugin is a candidate to be recommended to all customers by PRO ISP AS, Norway.

Known limitations

  • Links to documentation to resolve reported issues are shown to PRO ISP AS customers only.
  • This plugin will probably not report much if the site is not on a cPanel® managed server, but will do the test for HTTPS only.
  • This plugin was originally written for PHP 7.4 (recommended) and later, and for WordPress 5.2 (Site Health introduced) and later. It’s namespaced, has static classes and uses typed class properties. Also available for PHP 7.2, since typed properties are removed in this wporg edition.


  • Dashboard - At a Glance
  • Site Health Disk Space Test
  • Site Health Email Routing Test
  • Site Health HTTPS only test


Does this plugin add database tables, store options or adding lines to ´wp-config.php´?

No, not, none.

Does it require my login information to cPanel®?


Does it work on other web hosts than PRO ISP?

Yes, at least on some, but not tested much. Please report your experience. Use Reviews, Support or GitHub.

Does it work without cPanel®?

Very, very limited. The ‘HTTPS only’ security test should work, and disk used info, but max space test will not be performed and the result will just show ‘N/A’.

Can I contribute to this plugin?

Yes, visit it’s Github repo and create an issue, clone it and/or file a pull request.
