Today I installed the Yoast breadcrumb navigation plugin. My problem is the type-in-box “Separator between breadcrumbs”. As default, it says “»”. It’s all good till now. But when I want to use another char, like “›”, it displays (after saving the settings): “›”.
I had the same problem.
Just open up yoast-breadcrumbs.php and replace the code on line 52
from $opt[$option_name] = htmlentities(html_entity_decode($_POST[$option_name]));
to $opt[$option_name] = $_POST[$option_name];
