Still not working. When I upload/download with Fetch (set for “text”), there’s no space at the end of the wp-login.php file. The header error occurs. When I check the file in my site’s control panel browser interface, there’s a carriage return after the last ?> and it won’t go away, no matter how many times I overwrite or upload/download.
I have another WP blog on a different host that works just fine. I don’t understand how this could NOT be working?
