Thank you for this plugin. It works great and we have it active on many of our sites.
I did notice some errors though in debug mode and have resolved(?) them with the following two edits:
Plugin version: 3.6
I've wrapped the if statement:
with this if statement:
which solves an undefined index issue.
I've changed this line:
load_plugin_textdomain('wp_title_2', false, dirname(plugin_basename(__FILE__)).'/lang/');
since $abs_rel_path has been deprecated and is no longer functional(?)
Please correct me if I'm mistaken.
