Two weeks ago I install an aplication (cannot remember the name but it should help reducing spam comments)
Then it worked okay, except I got a warning (it said something I didn´t understood, so thought it was okay - at least my page worked, and I didn´t get spam)
But to day I have been log out of the system (the other users also). I only get this messege when I try to log in:
Warning: Missing argument 2 for wp_widget() in /home/l/a/sv_lassebaltzerdk/wordpress/wp-includes/widgets.php on line 76
Warning: Cannot modify header information - headers already sent by (output started at /home/l/a/sv_lassebaltzerdk/wordpress/wp-includes/widgets.php:76) in /home/l/a/sv_lassebaltzerdk/wordpress/wp-includes/pluggable.php on line 897
