Error 0 path cannot be empty with php 8.0.26

[visitmontaione]

Hello, If I clone my website, which is working nice on the main root, and I place a copy in a folder like /joomla4 (all configuration settings and .htaccess are fine), than I get this error:

0  Path cannot be empty
/home/customer/www/visitmontaione.com/public_html/joomla4/libraries/src/Cache/Storage/FileStorage.php:351

To make it works I have to downgrade the php versione from 8.0.26 to 7.4.

See attachments

Does anyone has the same issue? Solved?

Sounds for me like a joomla problem. Vm just calls the joomla router which fails. Do you use the last j4.2?

Thank you Milbo, yes I use the last Joomla 4 version.
By the way I've solved.

Kind regards.
