Description (last modified by SergeyBiryukov)

Beginning in 6.3.1, specifically with the change introduced in ticket #59116, Site Health incorrectly reports that "disk space is critically low" when the disk_free_space function is disabled by the web host.

Previously, in 6.3, Site Health correctly reported that it "could not determine available disk space" when the disk_free_space function was disabled.

Would you please share more information on the environment/configuration where this occurs? I was unable to reproduce the issue.

This seems to be an issue related to WPEngine having disabled disk_free_space

I'm also getting the same "Available disk space is critically low, less than 20 MB available. Proceed with caution, updates may fail." error as reported by @sdowney2002 in WordPress 6.4.

This is the environment:

  • WordPress 6.4
  • Server: Linux 5.4.0-1107-gcp x86_64
  • PHP: 8.2.11 (Supports 64bit values)
