OK I need help.

I installed both of the required items to have the UPC/ISBN boxes and its working internally. My issue is when you click on any item on the website, it directs you to an error.

1054 Unknown column 'pd.products_description2' in 'field list'
in:
[SELECT p.products_weight, pd.products_description2 FROM products p, products_description pd WHERE p.products_id = 1297 AND p.products_id = pd.products_id AND pd.language_id = '1' LIMIT 1]
I had this appear internally and it just went away on its own. I assumed it was a caching issue. But Now I clicked on products and its doing it externally now.

What caused this and how do i fix it....
