I have just upgraded to “5.1.1–nl_NL” and the issue still remains.
I have created a very simple CSV to reproduce the problem.
This file:
Type;SKU;Naam;Korte omschrijving;Beschrijving
Simple;1;Test;"Test Product";"Test Description <TABLE>"
gives me the “not permitted for security reasons” error.
But this:
Type;SKU;Naam;Korte omschrijving;Beschrijving
Simple;1;Test;"Test Product";"Test Description"
imports just fine. Is it just me? Or can anyone reproduce this issue?
