DreamHost One-Click Install Error Message

I recently set up a dreamhost account and bought a domain. I also used the one-click install version of Omeka for the website. However, when I try to access Omeka it gives me the following error message:

"Omeka has encountered an error
To learn how to see more detailed information about this error, see the Omeka Codex page on retrieving error messages."

I have read the installation instructions, but am unable to figure out how to get into the code in order to configure my database. I'm not very technologically savvy, so any help with this would be appreciated.
Thank you!

The more important thing will be following the instructions on retrieving error messages -- hopefully DreamHost got at least the database configuration done okay.

You'll need to go to the file browser from CPanel to find and edit the files in those instructions. There should be an option for something like 'show hidden files'. Keep that checked, in case you also need to edit the .htaccess file, again as per those instructions.

Once error messages are turned on, you should get much more information that you can pass on to us to help troubleshoot.
