I am having problems with this add-on. I made sure to download the v1.3.9h, as that is the version of ZenCart we are using, but I cannot get it to work! I unzipped the file and copied everything over as instructed... The problem is that when I pull the Sales Report in the Admin it is still the same old report from before the add-on, without the new filters and options. Is there something I'm missing? I'm VERY new to ZC so I have no idea where to look but HAVE tried to search the web and forums fir a possible solution...
