I've been using Wordpress 3.0 (installed w/ fantastico) and I decided to make a photoblog...
so I wanted to be able to use Flickr and add my wordpress blog there,
but I always get an error which says:

The endpoint you entered was not correct.
I searched around, and people on Flickr insist that this is a problem on my end. I've already tried downloading wordpress and re-uploading the xmlrpc.php file like a lot of people suggested... and flickr plugins don't seem to work real well.

Any ideas on what I should do?
