Print Friendly and PDF Button
Error: First argument is expected to be a valid callback, &# (2 posts)

    I just updated Print Friendly and PDF and now at the top of all of the pages in my wordpress install I get the following:

    Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, 'pf_head' was given in /home/content/##/#########/html/wp-includes/plugin.php on line 395

    I disabled the plugin and the page loads without the error. Any idea how to fix?

    (Please note, the #'s in the error are replacements I made, not sure of they are sensitive or not, but just wanted to be careful.)
