Warning: Call User Func Array expects parameter 1 to be a valid callback

  • Hello,

    I went to view my website this morning and I see that this error appears at the bottom of each and every post.

    Warning: call_user func_array() expects parameter 1 to be a valid callback, class ‘deprecatedSL’ does not have a method ‘log_file’ in/nfs/c10/mnt/151670/domains /justcoolstudio/html/wp-includes/plugin.php on line 406.

    I’m not really sure how I would go about fixing it, being that I’m not all that code savvy.

    How might I go about fixing this issue? Thanks
