Fix for PHP 7.2

When upgrading PHP to version 7.2 from 5.x, I received the following warning, which appears under each post the citation appears:

Warning: Use of undefined constant setting – assumed ‘setting’ (this will throw an Error in a future version of PHP) in <<link to the cite.php file>> on line 105

The fix to suppress this warning is quite simple.

Replace:

$edited_setting = str_replace($find_string, $replace_string, $wpcp_setting[setting]);

with

$edited_setting = str_replace($find_string, $replace_string, $wpcp_setting[‘setting’]);

That should suppress the warnings and resolve issues.
