WordPress has detected that your site is running on an insecure version of PHP

You may have an error saying : WordPress has detected that your site is running on an insecure version of PHP.

First, you should check your PHP version into your WordPress dashboard. Go into : Tools > Site Health > Info > Server

If you see that your PHP version is :

  • PHP version 5.2
  • PHP version 5.3
  • PHP version 5.4
  • PHP version 5.5
  • PHP version 5.6

To make WordPress works, your webserver needs at least PHP 5.2.4. But the recommendation is to have at least PHP 7.

The goal is to make a php update. You have to switch to PHP 7 (7.3 or 7.4 is recommended).

Here are steps to change your php version :

  • Create a Backup
  • Put the site into maintenance
  • Upgrade your PHP version to 7 (7.3 or 7.4) into your hosting. If you can’t do it, ask your host to upgrade the version of php
  • Try to navigate on the site, if there are errors, read bellow.
  • Remove the maintenance.

If something seems broken, remember to make an upgrade of your plugins & themes. If one plugin or theme doesn’t work with your PHP version upgrade, then you should consider contacting the developer or switch the theme/plugin.
