my website & blog is hosted through Yahoo! Small Business and since I upgraded to 2.6 last week I keep getting all these problems:
1. permalinks broken - switched to 'default' and they worked again, but I'd like to go back to month/postname (apparently, yahoo! doesn't allow .htsaccess files)
2. all my categories went 'blank' and i'm in the process of retagging every single friggin' post
3. yesterday my blog 'disappeared' with some sort of 404 error - all my files & database are on the server and I can access through Yahoo! but when I went to my blog, it was 404, as was my login/access to wordpress
4. today, i was able to intermittently access wordpress & edit posts, but then I started continually losing it to "Error establishing a database connection" - and now my blog has 'disappeared' again.
This is my first WP upgrade, so I used the long instructions & not the express mode. Is this just some dumb thing I'm not understanding, or is it Yahoo!?
Thanks for the help, all!
