Warning: array_keys() [function.array-keys]: The first argument should be an array in /home/account/public_html/wp-includes/widgets.php on line 686
Warning: Invalid argument supplied for foreach() in /home/account/public_html/wp-includes/widgets.php on line 686

atau ketika Anda harus login ke dashboard kena error :

Anda mengalami kesalahan seting pada widget text. Ini kesalahan umum, bukanlah khusus pada WP versi 2.6. Hal yang perlu Anda lakukan adalah :

1. Taruh perintah ini dalam file functions.php pada themes Anda : delete_option(‘widget_text’);
2. Refresh kembali halaman wordpress Anda.
3. Hilangkan perintah yang tertera di poin 1 dari file functions.php
4. Kemudian, perbaiki text widget Anda kembali.
