 Hi...

 Everything is working perfectly but i have a strange error when saving new
 settings on Settings > General (wp-admin/options-general.php)

 The page goes blank and only show this Error:

 Warning: array_search() [function.array-search]: Wrong datatype for second
 argument in /home/nettby/public_html/wp-admin/includes/plugin.php on line
 1044

 Warning: array_search() [function.array-search]: Wrong datatype for second

 (output started at /home/nettby/public_html/wp-
 admin/includes/plugin.php:1044) in /home/nettby/public_html/wp-
 includes/pluggable.php on line 856

 To get back I have to click back in my browser and continue whatever I
 want to do.
 The settings are saved and I only see this error when I click “save
 changes”.

 What could cause this error if I may ask?
