I'm trying to add a line to my .htaccess file, which I can see fine in Dreamweaver and also via sftp, but after I add the line, I get an error saying it can't save or can't upload. From Dreamweaver, I tried uploading two files, one of them the modified .htaccess file; the first uploaded fine, as normal, but not the .htaccess file so it isn't a password problem although it indicates that it is. What's the problem? Any suggestions? I'm trying to create a custom 404 page.
