I recently upgraded my blog to WP 3.0.
I have a hosted site and I run my blog in a separate (subdirectory) directory on my site. In other words, I have a separate Index page and my blog IS NOT in my root directory.
I am now getting "cannot resolve host" problems where my RSS feeds do not show up and I also cannot ping out, nor can I get even a search for new widgets!
All of this was working fine until I upgraded to WP 3.0 - and I suspect that I must change on the General Settings page the "Site address (URL)" to be http://www.yellow-stars.com and the "WordPress address (URL)" to be blog.yellow-stars.com - they both are blog.yellow-stars.com - which is NOT correct!
I'm I right? Well - WP 3.0 will not let me correct this even if I am right!
