Acme errors with old and new Certificates

Peque

Hi forum.
Setup is:
PFsense: Community Edition 2.6.0 ( But have Plus at home with same results)
ACME: 0.7.1_1

I'm trying to use our ACME in our PFsense - for let's Encrypt certificates. But after gratisDNS closed in Denmark ( and where moved to One.com) I cannot get my certificate renewing to work at all. I have 2 PFsense's and both can not renew the certificates.

A Simpel Question regarding the setup here with simply.com - it's asking for the API Endpopint URL - where the default is https://api.simply.com/1- and the recommanded are https://api.simply.com/2/

But no matter if I try through Acme/Simply.com or ACME/webroot - I'm still getting the same error - that my PHP make errors constantly. That ACME cannot create the Folder on PFsense.

I have tried with renewing the old, creating a new ACME account etc and nothing helps here
I'm getting this error regarding PHP errors, and can't get any further here:

And cannot figure out where all thgis goes wrong, when ACME is trying to renewing any certificates.
