I’d started to deploy a test version of SugarCRM 5.5 CE and an updated PHP 5.2.12 to a Windows 2008 server with IIS7 when I got an internal server error 500.<\/p>\n
What I found, eventually, was that while the installation of Sugar completed, the installation creates a web.config file that includes an instruction to ‘Add default document type’ of index.php to the site.<\/p>\n
The problem was that my server level settings already included index.php as a default document. The only reason I found it was when checking all the settings for the site in the IIS7 Manager it gives an error in the manager about the double up not being possible.<\/p>\n
Would have been more polite if IIS could simply accept that the index.php already is a default document and ignore it politely instead of doing a dummy spit type error and not running.<\/p>\n
In this case I just deleted the instruction to Add in the web.config.<\/p>\n
Another option is to include a instruction in the web.config to clear any existing default pages prior to adding the one(s) required for the current application. Like this:<\/p>\n
