I’m having the same problem. I just installed wordpress on a yahoo! hosted site, and while the control panel and front page of the blog work, that’s pretty much it. Anything linking off of the front page goes directly to a 410 error.
The guide that MichaelH posted worked to create a user for the database. I was able to install wordpress. However, after installation, when I went to view the blog, the only thing that worked was the homepage. Anything going off of the homepage gave me a 410 error, such as is documented in this post.
It’s like yahoo is punishing me for attempting to install wordpress. Ugggh.
thank you both, so much! i’m going to try these out tonight. hopefully one of them will solve my problem.
