Edit PHP configuration

Adjust upload, memory, execution and other PHP limits for this website.

Where Websites → your website → Advanced → Developer tools → php.ini editor

Enhance php.ini editor

What this is for

  • Inspect site-level PHP values.
  • Change a required limit.
  • Keep configuration changes small and traceable.

Before you start

  • Copy the exact setting named by the error or application requirement.
  • Record the old value and avoid raising limits further than necessary.

Take care

Very high limits can turn application bugs or abusive requests into resource exhaustion. Increase only as far as needed.

Steps

  1. 1

    Identify the exact directive and required value from the application documentation or error message.

  2. 2

    Open Websites, select the website, open Advanced, choose Developer tools and select php.ini editor on the left.

  3. 3

    Find the directive in the table. Inherited means the website is currently using the platform's default value.

  4. 4

    Use the row's three-dot menu to edit an existing directive, or select Add directive when the setting is not listed.

  5. 5

    Record the old value, enter the smallest value that meets the requirement and save the override.

  6. 6

    Keep related limits sensible: post_max_size normally needs to be at least as large as upload_max_filesize.

  7. 7

    Repeat the failed upload or process and inspect php-error.log in the PHP section.

  8. 8

    If the change does not solve the problem, remove the override or restore the previous value so the site is not left with an unnecessary high limit.

Check it worked

  • The editor still shows the new value after saving and refreshing.
  • Repeat the failed upload or process and confirm it succeeds without causing a resource or timeout problem.
