Problem since upgrading plugins

  • Have update some of the plugins and now get the following message when trying to log out of the site :- Warning: call_user_func_array() expects parameter 1 to be a valid callback, class ‘deprecatedSL’ does not have a method ‘log_file’ in /home/s16edin/public_html/wordpress/wp-includes/plugin.php on line 403

    Warning: Cannot modify header information – headers already sent by (output started at /home/s16edin/public_html/wordpress/wp-includes/plugin.php:403) in /home/s16edin/public_html/wordpress/wp-login.php on line 362

    Followed by further warnings about other lines that cannot modify header.

    How can I resolve this?
