When I change to a lower version I’m getting this note:
“Your site is running on an outdated version of PHP (7.4.33), which does not receive security updates. It should be updated.
PHP is one of the programming languages used to build WordPress. Newer versions of PHP receive regular security updates and may increase your site’s performance. The minimum recommended version of PHP is 8.3.”
Thats the reason I needed to update it.
