WordPress Error

Hello,

I got since 3 days ago a problem with my WordPress, all of a sudden my site isnt working anymore and shows me an error.

This is the error:
Notice: wp_enqueue_script was called incorrectly. Scripts and styles should not be registered or enqueued until the wp_enqueue_scripts, admin_enqueue_scripts, or init hooks. Please see Debugging in WordPress for more information. (This message was added in version 3.3.) in /home/hfoto/domains/dehaanfotografie.nl/public_html/wp-includes/functions.php on line 2758 Notice: Trying to get property of non-object in /home/hfoto/domains/dehaanfotografie.nl/public_html/wp-includes/functions.php on line 155 Notice: Trying to get property of non-object in /home/hfoto/domains/dehaanfotografie.nl/public_html/wp-includes/functions.php on line 155 Notice: Undefined index: rate in /home/hfoto/domains/dehaanfotografie.nl/public_html/wp-content/plugins/wp-postratings/wp-postratings.php on line 563 Notice: Undefined index: pid in /home/hfoto/domains/dehaanfotografie.nl/public_html/wp-content/plugins/wp-postratings/wp-postratings.php on line 564

I hope someone can help me to find the solution of this error and fix this. Its quit important because its a site for my job / hobby.
