I have this and the stock by attributes that are giving the same problem, but I have been asking for help for over a month on both issues on the plugin posts, but I have not gotten any help that will resolve this issue. I apologize but I am beyond frustrated at this point. I was hoping someone who may not be following those threads may know how to resolve these two plugins. My only other option is to delete zen cart and look for another product that may work without so many issues.
