I had the same problems, getting the error message:
Warning: array_keys() [function.array-keys]: The first argument should be an array in Testing\wp-includes\widgets.php on line 1044
Warning: Invalid argument supplied for foreach() in Testing\wp-includes\widgets.php on line 869
Turns out it’s an error you get when importing from a database using a different utf.
My brother managed to fix the problem by deleting the following code in wp-config.hp: /** Database Charset to use in creating database tables. */
define(‘DB_CHARSET’, ‘utf8’);
Good luck to others with the same problem!
