No Paul, you were definitely not the only one, in fact I would rather say people where everything worked without making at least tiny change in the config.php, are an exception
This however is nothing I can influence, some people for example have security restrictions for fetching content from external sources (causes problems with getting forecast from external source), others have restrictions in terms of writing files to the server (causes problems with caching) etc. But so far I have been able to find a fix in all cases and Javier was the last one where I really had to read a lot about servers to fix this.
The problem is I have never worked with servers, I use external webhosting and so I never really cared about this stuff, which is why it sometimes takes me time to get it right. The only person right now, who is still having problems, is Brian from WD
He wanted to test it as well, but sou far we are still having problems with getting the MySQL working.
And yes FAQ is something I definitely want to do and in fact something I even wanted to be included at first release, just didnt get to writing it yet
It will then be part of the wiki.
