I've just upgraded my site from 1.3.7 to 1.3.9h and this add-in from 1.4.6 to 1.4.12 and received the following error when I click on the link for stock by attributes under catalog. [select * from products_with_attributes_stock where products_id="66" order by sort ASC;] If you were entering information, press the BACK button in your browser and re-check the information you had entered to be sure you left no blank fields. I followed the upgreade instructions which stated that I need only replace the files, not make any database upgreades. What do I need to do? Thanks
