This was my first time using Amazon's AWS VPS server. I accidentally installed the Debian system, later discovering it was Debian 13.
After installing aapanel, I used the compile-install method to set up Nginx+PHP+MYSQL+phpMyAdmin in one go. I began building my WordPress site, and the default theme displayed normally.
However, when installing the Astra WordPress theme, I encountered the error: Could not store XML file in /wp-content/ folder.
I checked the official Astra theme documentation but found no solution—it only suggested contacting the hosting provider.
As a Linux novice, I noticed that Nginx has the www user, but php-fpm does not. I suspect this is the root cause of the issue. How can I resolve the www permission problem?
