Did you run the "Upgrade"? (copy the /upgrade folder to you site and go there - the upgrade should start automatically)? It will also clear your cache

Also, what PHP version are you using?

I uninstalled the XAMPP server and I will activate Apache, PHP and Mysql directly on Linux Mint

If the problem persists, I'll return to XAMPP and follow your steps. Thank you.

I was using:
No XAMPP 8.2.12, a versão do Apache é a 2.4.58, a versão do PHP é a 8.2.12 e a versão do MySQL é MariaDB 10.4.28.

Keep us posted!

I did what you told me, but the errors continued. These errors don't cause problems, so I'll leave it as is.

Thanks, Mamba.
