OK. Did you try with php 8.x.x?

>>> Please check the PHP ZIP module, then upload your WordPress to the latest version and try again.

I tried many times, in different ways. Always the same.

>>> If the problem doesn't solve, please use PHP 7.x on your local server for development.
OK, but I'm afraid whewn I'll go online. I hope will have no problems with server.

Hi, I'm trying to update php from 7.3.2 to 8.0.6, the latest version included in xampp (I'm working offline before to publish new site version made with your template... and so I can't give you access to my admin pages).

If I update home page has nothing but menu. I use a PenNews Child template with 6.6.0 version. I tryed to update to 6.6.1 but there's this problem and it doesn't update.

Upgrading the theme…

Backing up the old version of the theme…
