piler 1.4.4 does not work with PHP 8

[int]

I upgraded my installation of piler from 1.3.8 to the most recent version 1.4.4 from the download page https://www.mailpiler.org/download.html
piler-1.4.4 (~5.7 MB), 2023.09.04. SHA256: 547052e4b3da6d17a63dd5b0aa717f0f23cd61825de2afdca28adc19c36bafd5

I also upgraded the OS from CentOS7 to Alma Linux8

Since the Installation manual https://www.mailpiler.org/installation/ states that mailpiler does support PHP 8.x
I switched the PHP installation to version 8.2 from the REMI EL8 repository

But when piler is run with PHP 8 the login page works, but after entering the login credentials it crashes with these errors:

 thrown in /var/www/piler/system/language.php on line 56

I switched to PHP version 8.0 from the REMI EL8 repository as well as PHP 8.0 from the Alma Linux system repository but got the same errors.

When I use PHP 7.4 piler works fine.

Your upgrade might be incomplete. By default piler installs the gui to /var/piler/www, but you are using (probably the previous piler release) from /var/www/piler. Version 1.4.4 has no each( ) calls.

The wrong install path was indeed the cause of issue. I overlooked that the path changed from /var/www/piler to /var/piler/www and adjusted the Apache configuration accordingly. Many thanks for the quick and helpful feedback.

You are welcome.
