Hi,
The .htaccess file is not supposed to be publicly visible, so it’s a good sign that you can only access it when you’re logged in onto DreamHost. I get no error message when I preload your zip file in a project on farm.pcibex.net: the Log tab of the Debug window confirms that the download is successfull (“[14:15:16] Download of https://www.maddiegilbert.com/abxziptest/abx_zipped.zip complete (PennController: 0)”)
