Nextcloud on Ubuntu server - php question

Hello all,

I am asking some help on the forum regarding the video and tutorial named “Build an Awesome Nextcloud Server (Updated for Ubuntu 22.04!)”.

I installed Ubuntu Server 22.04 LTS on an old machine planning to install my own “Nextcloud instance”. As I already solved several issues in the past with the help of Jay’s video, I try to keep the pace.

During the process I already add a few concern with apache2 that I had to install and reinstall several times but I finally succeeded.

My main concern occured after the modifications of the php.ini file. I checked this section of the videos several times and I still do not see where I did something wrong. Basically, before updating the php.ini, I had the apache2 default page when writing the ip address of the server in the bar. After updating the php.ini and rebooting the server, I had the message error attached and I do not see what to change.

My first thought was about a potential updated version of the php but I saw in the forum that version 8.1 is a rather recent version.

At that point, really was working really easily because this is my first server and I am learning all of this. May be it is a detail but before setting the php.ini, I was even able to see the login screen of Nextcloud.

Do you have any idea or suggestion to me in order to help me finding the root cause and undestand what is laying behind?

Thanks a lot and I wish you a nice day.

Kind regards,
