.htaccess /changing permissions in dreamweaver

my problem is that the links do not work when I change the permalinks from default to a custom setting because the “.htaccess file is not writable.”

i tried changing the permissions to 666, then 644, then practicially every other combination I could think of.

Does anyone know what im doing wrong?

I have already edited the file and re-uploaded a million times. I have changed the file permissions through Dreamweaver and through the server Cpanel but when I try to change the permalink structure, I still get the message that the .htaccess file is not writable.

also, I get this error:

Not Found

The requested URL /blog/about/ was not found on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

yeah I tried that. I tried changing the permalink structure and then when I go to view a page, it says “The requested URL /blog/about/ was not found on this server.” I do not know why that is happening since I have changed the .htaccess to include the code that it tells me to add.

Here is the blog I’m working on:

While you’re there, can you possibly tell me why the “test” links under “Recent Posts” are not working? They seem to only work when I place the div higher.

Thanks!
