Update PHP Version for Wordpress

Do you have any tips for upgrading from php 7.3.3 to 8.2.8 on a Wordpress site.

I've been trying for 3 months and I can't take it anymore.

Every time I get unthinkable errors, I can't access Wordpress...

I try to modify and edit all the files that could have even a small impact on the way wordpress works, but nothing works.

I'm just completely blocked.

I'm even willing to pay someone to give you an idea of how desperate I am....

HELP PLEASE What's also very inconsistent is that when I run the command

php -v

or when I launch a php file with phpinfo(), it tells me that I'm using 8.2.7.

However, my Wordpress site displays that it's using 7.3.3

And my VPS host made it clear that I should go fuck myself for their support, even though they're the ones who provide this crappy version of php when Wordpress is installed...

In short, it's just hell and I can't do it...

I tried to :

• Uninstall and reinstall php so as to only have the version I'm interested in (8.2)
• Edit the .htaccess file so that Apache has to use the version that I want
• sudo a2enmod php8.2

And so many things that I don't remember...
