I took over a Drupal 7 site and was setting up a local environment in MAMP on windows. At first I got a white screen. I went to updates.php and ran a couple updates and could then get into the site. Then none of the CSS was loading, so I unchecked aggregate CSS and JS. My drupal CSS loaded, but still not my front end. It looks like it's trying to load styles from the OMEGA theme. The site theme is a sub theme of that and none of the CSS declared in the info is being loaded. I'm using the exact files from the live site.
Any suggestions of what I can do? Feel free to ELI5 as I'm not super comfortable in drupal.
