This is how sidebar for new created blogs looks like. I adjusted it to pull 'Biographical Info' which you can edit inside 'Edit User' area. Just like you can see here on my portfolio: http://marko.boonika.net/

After to 2.8.6 upgrade it wont show that info for newly created blogs: http://illustr8a.boonika.net/

But, as you can see on my portfolio, old blogs stayed untouched.

instead of doing an echo of the description, do a var_dump($userdata). See what you've got in there. Is it different between old and new users?

If you are talking about the code than no, it is the same default theme.

No, I'm saying change your function in the code you posted.

function print_profile() {
       global $wp_query, $blogownerid;
       global $wpdb, $blog_id;
	$blogownerid = $wpdb->get_var("SELECT post_author FROM wp_" . $blog_id . "_posts");
$userdata = get_userdata($blogownerid);
 //if ($userdata->description != '') {
//echo substr($userdata->description, 0, 180); }

var_dump($userdata);
}

See what you're getting back for user data.

Aha... sorry, I misunderstood this part 'Is it different between old and new users?'

Thanks, will try your solution.

First, I don't think that I wrote it properly:

var_dump($userdata->description, 0, 180); }

Second, nothing changed on that last blog I created. Empty space, just like before.

No, I specifically DON'T want you to limit it to the description field. I want you to dump the entire variable (just like I wrote in the code). This is called debugging. This is how you solve problems. You dump out information so that you can look at it. This is not your ultimate solution. This is a step on the way to the solution.

Well, as one of your biggest admirer I can only say 'thank you'. But as a designer (wannabe programmer) who always fights with the code (ask andrear) I can only say 'these steps to final solution are too much for me at this moment but I will sure investigate it in following days'.

Cheers,

Okay, here's my take, having done the debugging for you. $userdata->description is not defined unless someone actually fills out their bio info. So, your new users haven't filled out their bio info.

That's my take.
