Error message when posting/scheduling posts

    I’m running the latest version of WordPress at my blog. For the last couple of months however, when I schedule or publish a post, I get an error message. The post still works and everything looks okay at the front end, but I don’t know why I’m getting the error message and I’d like to fix whatever’s wrong so I don’t keep getting it.

    The errors I’m being notified of are:
    Warning: strtolower() expects parameter 1 to be string, array given in /home/kaetrins/public_html/wp-includes/formatting.php on line 1881

    Warning: Cannot modify header information – headers already sent by (output started at /home/kaetrins/public_html/wp-includes/formatting.php:1881) in /home/kaetrins/public_html/wp-admin/post.php on line 197

    Warning: Cannot modify header information – headers already sent by (output started at /home/kaetrins/public_html/wp-includes/formatting.php:1881) in /home/kaetrins/public_html/wp-includes/pluggable.php on line 1179

    Can anyone help me with this? I’m not very experienced with html or coding generally so I don’t want to muddle about and make a mess.

    My website is: http://www.kaetrinsmusings.com

    Let me know if any other information is needed.

    Thx
