Hello: I purchased a theme that uses a custom post type for "portfolios". I need to add an additional taxonomy for tags. I have installed a plugin called simple taxonomy. I have installed the plugin and get the new taxonomy to appear on my portfolio posts. But I cannot click or add them to the portfolio post. It is as if I do not have permission or rights to add these. I need help with getting this configured properly to allow me to add these new tags I have titled labels.
