My website is running on Magento 2. I have migrated data from Magento 1.x to version 2.1 using UB data migration tool. Now I am planning to upgrade Magento 2.1.3. After Magento upgrade
I am unable to save new products. It shows error:
SQLSTATE[HY000]: General error: 1449 The user specified as a definer ('rb_magento2'@'localhost') does not exist, query was: INSERT INTO
required_options) VALUES (?, ?, ?, ?, ?, ?)
The user rb_magento2 is or live Magento database but I have created a copy of Magento on a new server with the different username.
