[ERROR] Duplicate entry '0' for key 'PRIMARY' #83636

Hello,
For product with SKU 759_10378 product_availability field gets Περιορισμένη διαθεσιμότητα Επόμενη παραλαβή as value which is breaking the insert query. It gets error "Data too long for column 'product_availability' at row 1" and so product is not inserted. product_availability field can take only 32 characters in VirtueMart table. That is also the reason for Duplicate entry error. You need to make sure this value is less than 32 characters.
