Not sure how this happened, or when. 

I have had a pretty big problem recently when out of nowhere, our news feed went missing, completely invisable. It seems like the tag parsed but isn't outputting the news feed articles on home page.

So I looked around and I found a random user was setting permisions , but is it true? or is this a bug in the admin panel?

This user is not a moderator or administrator and only had "user" rghts, which don't let you edit any content on the site.

Now I see under other sections this user is listed under the "set by" colum for user rights on the news cat too... WTF???

Anyone have this issue? Because of this I was trying to just upgrade from Genoa all together to Siena, which went HORRIBLY, the upgrade script just wasn't working. If you can help me on this issue, or the upgrade issue, or think the issues could be related, that is awesome let me know.

my other topic regarding update issue. http://www.cotonti.com/forums?m=posts&q=7593&n=last#bottom
