I have bought a installed your excellent looking "Virtuemart excel-like product manager". I have installed it on a local server for a webshop that I am developing that currently has about 600 products.
When I call up the "Virtuemart excel-like product manager" I get a spreadsheet table with the correct number of lines, but will all ID, Stock = 0 and other fields completely blank!
The filters on the right side work, The category options are correct, and if I type part of a product name then the resulting number of blank lines match the correct number of such product.
I attach a screen of the page (& also firebug). Would anyone have any idea what could be causing this?
