Issue Cannot change PHP version of website

mpll

New Pleskian
Server operating system version
CentOS Linux 7.9
Plesk version and microupdate number
18.0.64 #1
I have a website with PHP 7.3.33, and changed it to 8.3.13. The issue is that even the dashboard shows the new version, the change is not reflected on the website, that keeps using 7.3. Clicking on phpinfo() also shows 7.3.

I've restarted PHP with no luck.

NOTE: I don't have litespeed

Thanks
 
Under Tools & Settings > PHP Settings, is there the 7.3.33 enabled? If not, enable it and then apply the change again to 8.3.13 on the domain.

Other than this, I cannot remember other situations right now that could cause this without Cloudlinux or Litespeed
