Hello, I have tried long to find an answer to my question. Most posts refer to issues involving multiple sites using a single code base, but what I want to do is to build a Drupal 7 site in a subdomain of a Drupal 6 site that is up and running. In my shared hosting environment I have created, in cpanel, a subdomain called mysubdomain.mysite.com. I have created a new database and user for the D7 site and I have extracted the Drupal 7 files and folders into the subdirectory that cpanel created for mysubdomain.mysite.com, but when I try to navigate to mysubdomain.mysite.com/ or mysubdomain.mysite.com/install.php or mysubdomain.mysite.com/index.php I get this error message:
"Internal Server Error The server encountered an internal error or misconfiguration and was unable to complete your request. Please contact the server administrator, firstname.lastname@example.org and inform them of the time the error occurred, and anything you might have done that may have caused the error. More information about this error may be available in the server error log. Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request."
I have tried editing the .htaccess file in the subdomain's directory (let's call it "mysubdirectory"). I tried "RewriteBase /mysubdirectory" and "RewriteBase /mysubdirectory/" and "RewriteBase /" but I keep getting the same error. What do I need to do to get the Drupal 7 site's install utility to launch properly and have the D7 site run independent of the D6 site?
