The installation is in a clean Modx Revo 2.7.1

Thanks!

UPDATE:
I did update to php 7.0 version but that not solved the problem, I did install Bcmath PHP module and now it’s working!

what php version is that server using ?

php 5.4 in a Red Hat Server.

What is the minimum required pre-requisites for Fred?

I have it installed but I cannot display the page, I’m also getting errors (different error to this thread)
However I saw the question asked about php version but no answer if 5.4 is ok or not.
I’ve looked in Fred documentation but I cannot find minimum re-requisites anywhere so I’m wondering if I need to download or upgrade anything else.

It is hosted on a shared server running php 7.0.33

Hi, I’m pretty sure Fred needs PHP 7 or above. (Although I could be wrong)
PHP 5.4 is very old.
It also needs MySQL 5.7 if you’re using UTF8mb4 encoding on your database. (Although 5.6 should be compatible in the next release)

What happens when you try to display a Fred page? Any errors related to it?

In regards to @yuliyepes original post. That looks like a normal install log - I can’t see any errors there. It will skip those objects if they already exist.

Fred will work best with the latest 7.1.x as the minimum. From the upcoming docs update:
