Whenever I try to search for a blog entry or even a word on my blog I get this error:
Warning: call_user_func_array() [function.call-user-func-array]: First argumented is expected to be a valid callback, 'fb_sitestat_filter' was given in /home/jandj/public_html/designcreatology/b/wp-includes/plugin.php on line 57
Can someone please help me understand what this means? But more importantly how to get rid of this message.
My blog is:
