Hello, I am using Zen 1.5.0 and when I enable the UPC/ISBN/EAN in the configuration to TRUE and try to "confirm" I get this error: (

Google Merchant Center Feeder v started 2013/02/18 16:42:36
Feed file - /home8/wwrepair/public_html/parts/feed/google/wwrepair_products_en.xml
Processing: Feed - Yes, Upload - No
WARNING: An Error occurred, please refresh the page and try again

If I change the UPC/ISBN/EAN back to false, it will upload only some of my products. I do use the UPC field but not ISBN (Numinix Product Fields Module). The last upload had 3017 and after trying to get the UPC to work it only uploads 1645 (again I have to disable the UPC filed in admin or I get an error). Any help is greatly appreciated. Thank you!

I checked my debug log and this is what is says:
