How to change your PHP version

1. Open your Pressy and go to PHP in the sidebar.
2. Stay on the Version and limits tab.
3. Pick a version. Each tile says whether it still gets security fixes.
4. Confirm.

Switching restarts PHP within a few seconds, and the site is briefly unavailable while it does.

Which version to choose

Choose the newest version that does not break your site. Newer PHP is faster and, more importantly, still receiving security fixes.

A tile marked No security fixes is past end of life. It keeps working, but nobody is fixing its security holes any more. Move off it.

Test it first if the site matters

1. Create a staging copy.
2. Switch the dashboard into staging.
3. Change PHP version there and click around — checkout, forms, admin.
4. If it is fine, switch back to production and change it for real.

If the site breaks after changing

Change it back. Same screen, same three clicks, and you are running again within seconds.

Then find out what could not cope: switch on WP_DEBUG and WP_DEBUG_LOG on the WordPress → Advanced tab, reload the broken page, and read PHP → Error log. The entry names the plugin or theme.

The usual answer is a plugin that has not been updated in years. Update your plugins and try again, or replace the plugin.

When to write to us

Write to us if the site does not come back after changing the version back. Say which version you moved from and to.
