I have recently found that the import feature has suddenly started only showing the "Product ID*" field.
we have recently set up Cloudflare and Express Cache.
We have had to change "Check the IP address on the cookie" to No otherwise we can't import images (Due to Cloudflare)
I have tried disabling the features of cloudflare and disabling the Express cache Module. Neither option has returned the capability to import csv files.
this is the case on import types;
Combinations
Products
Categories, Customers, Address, Manufacturers, suppliers only show "ID"
Looks to me that it is not reading the csv file properly, so i have also tried an old csv that i know worked previously and this has not helped.
