The PHP error say : Connection Refused by fetching the file via HTTP
Check on the Host if the Hostname www.si-community.com points to the correct server (it self)
and try to make a HTTP to the resulting IP to see if you get the txt file.
There are some think that could be happen :
- in the /etc/hosts is maybe the hostname pointed to 127.0.0.1 - and the apache doesn't listen to 127.0.0.1
- the hostname resolution (DNS) doesn't work correctly
- a ip tables is installed that prevent port 80 from localhost to myself
Anyway, it would be better to find the include and replace the creepy fopen HTTP with a direct file access by using DOCUMENT_ROOT to access the txt directly without the http selfquery
If you need moar halp - ping me ^^
