    Debug setting

    For extra debug information, add this line to your wp-config.php or in another plugin:

    const WF_DEBUG = true;

    Known limitations

  • Requires PHP `shell_exec´ to be available
  • Reports data from your own cPanel® server, not remote
  • Reports data from your cPanel® server, all sites and all other web or cPanel® applications, in case more than your WordPress is installed on it
  • Links to documentation to resolve reported issues are shown to PRO ISP AS customers only.
  • This plugin will not show much if the site is not on a cPanel® managed server, but will do the test for HTTPS only.


  • Dashboard – At a Glance widget
  • Site Health Disk Space Test
  • Site Health HTTPS only test
  • Dashboard – Resource usage & errors widget


Does this plugin add database tables, store options, scheduled tasks or writing to `wp-config.php`?

No, not, none, no.

Does it require my login information to cPanel®?


Does work if ´shell_exec´ function is disabled in PHP?


What if I don’t want the cPanel® Resource Usage widget (gauges)?

Close it with the up arrow icon, or hide it using Screen Options (the top right hidden panel) – as usual. No data will be fetched from cPanel® while widget is closed or hidden.

Does it work on other web hosts than PRO ISP?

Yes, should work on any cPanel® hosting.

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?

No longer. Please see WebFacing™ – cPanel® Email Accounts management & Account backup
