PHP settings

Each website has its own PHP settings. Changing them affects only that website. Open the website and go to Hosting › PHP.

Change the PHP version

Pick a version from PHP version. The change starts as soon as you choose it; there is no separate save.

The list shows the PHP versions installed and working on the website’s server, from PHP 8.0 to PHP 8.5. If none is listed, the page says “No healthy PHP runtimes were reported”; click Check again after a moment.

Tip

Before moving a live website to a new PHP version, try it on a staging copy first. Old plugins and themes are the usual reason a site breaks after an upgrade.

Change PHP limits

1. Choose new values from the lists.
2. Click Save changes.

Setting	Choices	Default
Memory limit	128 MB to 1 GB	256 MB
Max execution time	30 to 600 seconds	300 seconds
Upload max filesize	32 MB to 1 GB	128 MB
Post max size	32 MB to 1 GB	128 MB
Max input vars	1,000 to 10,000	5,000
Max input time	30 to 600 seconds	300 seconds

A setting you have never changed shows a small Default label.

To accept bigger uploads, raise both Upload max filesize and Post max size. If the upload limit is higher than the post limit, the page warns you, because PHP refuses any upload bigger than Post max size. The web server’s own upload size and timeout limits follow these settings, so you don’t need to change anything else.

Other settings on this page

Depending on the server, the page can also show:

• Page cache: Enabled or No page cache. See Caching and Redis.
• HTTP Strict Transport Security: Enabled tells browsers to always use HTTPS for this website. Turn it on only when HTTPS works on every address the website uses.

These two apply as soon as you choose them.

Restart PHP

If the website seems stuck, click Restart PHP-FPM at the top of the page, or Restart PHP in the website’s actions. Pages may pause for a moment while PHP restarts.

Copies and moves

When you clone a website, create a staging copy or move a website to another server, its PHP settings go with it.
