Install Help Needed

Hi All,

Its been a real learning curve with PHP and MYSQL over the last couple of days to get Xerte installed!

I think my install is complete however I have the following problems:

1. when I navigate to http://hostname/xertetoolkits/index.php - I get a 500 internal server error
2. when I navigate to http://hostname/xertetoolkits/management.php - I get the login page and enter the account details as suggested in the install guide and then I get another 500 internal server error

I can navigate to http://hostname/xertetoolkits/setup fine, and it tells me the toolkit is installed and to click the link to the main site however I get a 500 internal server error....

I think maybe I have a PHP config issue somewhere but do not really know enough about it to fix!

My environment details are:
hosted in an internal environment
server 2008 r2
IIS 7
MYSQL 5.5.32
PHP 5.5.2

Any help would be great.

Thanks
