PHP version on the web server

The PHP version on the web server is 8.0, and my website works fine. However, when I upgrade the web server to PHP 8.2, my website no longer displays. What could be the reason?

In RapidWeaver Classic PHP is set to 8.4.4

What do you mean by no longer displays, an empty blank page?

Is this in Preview?
If so check the logs: Elements Menu > View > Web Server Logs, are there any messages that might help?

If in on your remote host, check the PHP logs.

The version of PHP you set in RapidWeaver is only for Preview mode, it doesn’t change any code in your project. And won’t affect the published site.

Are you using any third-party plugins or stacks that use PHP? I’d suggest checking they are compatible with PHP 8.2+

Hope that helps.
