HTTP input character conversion is improperly configured
mbstring.http_input must be left empty. You can check the current value on the PHP information page.

But for your case, in short, you can simply ignore this error because the setting it’s complaining for no longer exists/functional on PHP 8.2 as it is a deprecated feature.
For the complete answer, you simply need to satisfy phpBB, you can always add the following 2 lines in the .htaccess of your root folder. It does not actually do anything, but it should remove the error if phpBB can read these values only to determine if mbstring is installed (it is installed by default).
In your .htaccess (in your domain’s root and not phpBB’s) add the following two lines:
By default, the mbstring.http_input is set to an empty string. However, if you have ever used the Alter PHP Config option in the control panel, it will have likely injected a .htaccess rule that overrides the default server configuration.
Annoyingly, the Alter PHP Config tool in the control panel does not let you not configure anything for the mbstring.http_input setting, it must be set to something.
So for now, I would suggest to open the htdocs folder for your website in the file manager, edit the .htaccess file and remove the line that says php_value mbstring.http_input auto.
Please do note that any time you use the Alter PHP Config menu in the control panel, this line will be restored. You could try to use the PHP Options menu in the client area instead, which doesn’t set this setting.
