I was using CSV to import my custom post types (I have about 2500) Everything was going fine, I was importing about 100 at a time. I checked the frontend of the site at about 1500 imported and it looked good. I kept going and checked again at 2000 and now my site won't load. Well the header of the site loads, but nothing else. My WordPress backend still works fine.
When I look in Firebug I get a
"NetworkError: 500 Internal Server Error - http://mysite.com/"
I can't figure out how to get my site back online now and it must be something this plugin has done :(
