Post installation

I'm getting this error everytime I view a user profile:

Warning: Invalid argument supplied for foreach() in /.../modules/user.module on line 1164

That line looks like this:
foreach ($data as $category => $content)

Any ideas? The only clue I can give is that I had been modifying profile and user, but I backed them to 4.4.1 base when I started getting errors...

why does drupal not use named html entities for accents? (ie ã = ã)

sorry if this has been discussed before, but i couldn't find anything about it using the search box.

My 4.4 Drupal is up and running just fine. However, when I created my first admin account, I used my personal email address. Now that the site is live, I've changed the admin account's email address to be my client's address. I've also changed the init field in the user database to also match the client's address.

But, still, when I create a new user account, the email generated comes from the old email address, not the new one. Any ideas? Where does that email address come from?

Yesterday I upgraded my site from 4.4.1 to CVS, and while everything seems to work well, I have one problem.

In the 'Edit menu item' page ( mysite/admin/menu ), any changes I made does not registered. That is, when I tried to enable or disable any some items, I took me to the edit page, but after clicking 'Submit', there was no changes. ('disabled' still 'disabled' and 'enabled' stil 'enabled').

I do a clean install on my local machine and it works fine. But I can't figure out what is broken on my real site. Could someone suggest where it might go wrong?

I have trip_search and taxonomy_browser modules installed on my site. Both of them help users to navigate content of the site and find information they need. And both of them can be accessed through two different links in the main menu.
So i thought it will be useful and more convenient for my users to unite this modules and show them on one page which will be accessed by means of one "search" link in the main menu.

is it possible to have a poll inside another node type... like a story w/poll?

if not, are there plans for this type of functionality in future releases?
