Not sure what happened here, but my last spreadsheet put me over the 20,000 items, and coincidentally I can't view my categories/products from the Catalog tab in Admin anymore. Not sure if anyone else has had this problem, but I plan to have many, many more than 20,000 products in my store, so I would like to fix this if it is possible. Could images be a problem? Image size? Just too many products, maybe? If there is a better version of this Zen Cart that costs money, can someone clue me in as to where to find that and how much it may be? Any helpful info would be great!!
