Hi,
big kudos to you Flynn for Montezuma theme, I love it, and can't imagine to work with something different. This theme and your ways of solving site management defined my WP understanding. I have a site with 300+ posts, several pages and categories, etc. Since long time there is a log line which appears to show randomly and is looking like this:

Code:

I'm unable to find any solution to this. I have read a similar topic here on the forum, where you had already investigated similar problem. You have said that all posts should have it's category assignement. I checked this and all of them have at least one category. However, there is no category 'Uncategorized' (I changed it's name). I suspect that some IDs could be set wrong, dunno.

Could you be so nice and find some time to help?
