Can you show me an example on your blog? Or better yet, show it to me on my blog? http://jon.limedaley.com/ I just did a search for "test", and it came up with 8 pages, which seemed reasonable, though I didn't look through all of the pages to make sure that all of the articles were unique.
fulltext was false, i had set to true and now seem to be good. I have some post in draft, but not more than 10posts. i'll do it when i'll be more in confidence with this program, even i'm little bit scared about upgrade
The "upgrade" is simply copying in the files. There isn't any change to the database. It is true that it is possible there are new bugs, but there are lots of things fixed as well: http://bugs.lifetype.net/roadmap_page.php
