I am upgrading from 2.2.5 to 4.0.3 through 'Store Import' add-on. Everything worked well except product description in the 'product tab' is missing. When I checked through admin panel Product description appears to be fine. Even product 'Quick View' on web site shows the description. When checked through Admin panel top navigation Design >> Product Tabs only 'Description' tab is missing, all other tabs are fine.
Is there any way to get the 'Description' tab back? Where can I edit the code?
I got the same problem. So how did you solve it?
