System Requirement Issues

Certain SpeedyGo features may fail to activate if required PHP extensions are missing or if server resources are insufficient.

31.1 Problem #

If your hosting environment does not meet minimum requirements, some optimization features will remain disabled.

Technical Context #

  • Continuously checks: extension_loaded('gd')
  • Validates available storage using: disk_free_space()
  • Verifies WebP support capability
  • Monitors cache directory accessibility

If any of the following conditions occur:

  • The GD Library is missing
  • WebP support is not enabled
  • Disk space is insufficient

Persistent admin notices will appear inside the WordPress dashboard.

31.2 Solution #

To resolve the issue:

  1. Log in to your hosting control panel (cPanel / Plesk)
  2. Go to PHP Extensions or Select PHP Version
  3. Enable:
  • gd
  • imagick (optional but recommended)

Also ensure sufficient free disk space in:

wp-content/uploads/

If extensions cannot be enabled manually, contact your hosting provider for assistance.

31.3 Best Practice Recommendation #

  • Use PHP 8.0+ for best performance
  • Monitor available disk space regularly
  • Verify WebP support after enabling GD or Imagick
  • Clear admin notices after resolving the issue

Proper server configuration ensures all SpeedyGo optimization features function correctly and reliably.
