How to Edit PHP Settings with MultiPHP INI Editor

MultiPHP INI Editor changes common PHP settings through a simple form — no need to hand-edit php.ini. It is the right tool for upload-size and timeout tweaks.

Step-by-step

  1. Open Software → MultiPHP INI Editor in cPanel.
  2. Select your domain from the dropdown in Basic Mode.
  3. Adjust the common directives shown as toggles and boxes: memory_limit, upload_max_filesize, post_max_size, max_execution_time, display_errors.
  4. Set sensible values — e.g. upload_max_filesize 64M, post_max_size 64M, max_execution_time 120.
  5. Click Apply. Changes take effect immediately for that domain.
  6. Use Editor Mode for advanced directives not shown in Basic Mode — paste valid php.ini lines and save.

💡 Good to know

  • post_max_size should be equal to or larger than upload_max_filesize, or uploads silently fail — see upload size.
  • Turn display_errors off on live sites so visitors never see error details.
  • Changes here apply per domain, leaving your other sites untouched.
