Errors in plugin code breaks the website

Hi,

There are some errors in code, which breaks the website if you turn on WP_DEBUG

Some of the errors are inside pw_save_term() function.
Line 968: if (current_user_can($objTaxonomy->cap->edit_term)) {
needs to be like: if (current_user_can($objTaxonomy->cap->edit_terms)) {
$objTaxonomy->cap->edit_terms

Also variable $taxonomy is not defined in that function. I assume that something like this is missing inside pw_save_term() function:
$taxonomy = $_POST[‘taxonomy’];

WP version 4.0
Theme: Twenty Fourteen 1.0

Regards,
Ivan
