At first, I was getting the message saying that I didn't have a file on the server or it wasn't writable. So I then uploaded one and made it writable.
Now when I make the change so that permalinks are available, the next thing that happens after I submit the change is that I get the Forbidden 403 error. Huh? 403? Why?!
So before I even had an .htaccess file in the directory, it always said successful. But once I either copied the info into the .htaccess and saved it, or when I made the .htaccess writable and WP changed the information itself, I could and still can not access the blog or control panel area without deleting the .htaccess file itself.
