Unknown column 'GroupingID'
I am using version 4.5 - the page is products_results.php in the admin area.
I've attached a screen print of what the page looks like when it screws up and a zipped copy of the page itself. This only occurs on the page where the "damaged" product appears. The previous | next products_results pages look perfectly fine.
Here's the process that made the page screw up:
Entered a new product - gave it a name, price, picture, description and selected categories.
Entered Advanced Options - up to the third entry everything is fine
then on the fourth entry - the admin product_results goes haywire (only on the page that this new product appears).
To get everything to look normal again I have to remove the Advanced Options on that particular product.
