Hi,

i had problems installing the subsites module and overcame them like this.
I'm using a test envoronment on osx with xampp and silverstripe 2.3.0-rc2.

Installation:

• unziped the latest version of subsites and genericdataadmin below htdocs/silverstripe (root folder of silverstripe)
  
• made a link in the root folder with
  

  sudo ln -s modules/genericdataadmin/tags/rc/0.1/ genericdataadmin
  sudo ln -s modules/subsites/trunk/ subsites

  
  
• Issued a http://localhost/silverstripe/db/build?flush=1 to see the subsite item left of the helm menu when calling the admin section at http://localhost/silverstripe/admin/
  

Setup:
When opening the subsite section under http://localhost/silverstripe/admin/subsites/
I got the error: Notice: Trying to get property of non-object in line 113 which is this code:

• After I made a quick hack modifying the line to:
  

  113 return $list; //->First()->Title;

  
  
• loading the page succeeded.
  This confimed my suspicion that the db is not proberly initialised on install and there is no trap for this kind of error, which should be.
  
• After creation of the first subsite and undooing my hack, it works now.
  
• However, the error comes back if i delete the last subsite. So if there is a php crack who can fix this or even a developer, great!
  

Cheers
Bj

Hi BSirius

Thanks for your post.

I can confirm I had exactly the problems you described and your work around worked

The subsites module is working right now - without setting symlinks. I just forgot to install the genericdataadmin module.

For everybody experiencing similar problems: Here´s how I installed subsites.

1. Install SilverStripe 2.3.0-rc3 http://www.silverstripe.org/assets/downloads/SilverStripe-v2.3.0-rc3.tar.gz
2. Install genericdataadmin module (Daily Build) by placing the folder "genericdataadmin" in the root folder of SilverStripe http://doc.silverstripe.com/doku.php?id=modules:genericdataadmin
3. Rebuild database by calling http://localhost/silverstripe/db/build?flush=1
4. Install subsites module by placing the folder "subsites" in the root folder of SilverStripe (http://doc.silverstripe.com/doku.php?id=modules:subsites). I downloaded the trunk version in the provided zip file.
5. Rebuild database by calling http://localhost/silverstripe/db/build?flush=1
6. Go to the admin area of Silverstripe and clear the cache by calling http://localhost/silverstripe/admin?flush=1
7. The "Subsites" tab appears in the admin area

Configuration of subsites
As I wanted to use multiple domains with different pages, I configured subsites to allow setting up any domain, instead of just subdomains. To do this just enter the following code in the _config.php file of your sites folder.

mysite/_config.php

This code allows you to set up any domain ending with '.com' od '.de'.

Hi ulysses,
it looks like the necessary tables of the subsites module aren´t installed.
Did you follow the steps i described in my previous post?
First install the genericdataadmin module
Then call http://yoursite.com/dev/build/?flush=1
Second install the subsites module
Then call http://yoursite.com/dev/build/?flush=1 again (This should give you some new tables called something with "Subsites")

The only other problem I could think of is that you copied the wrong subsites folder. As you are using a trunk version the folder structure should look something like this:
modules/subsites/trunk/CONTENT HERE

What you need to do is copy the "trunk" folder with all its contents to your webserver root and rename it to "subsites". Then rebuild your database.
