Hello Surani,
Today is 13:11 09.03.2017 and i use:
Magento CE Ver: 2.1.5 Apache 2.4, Win 7, MySQL 5.7.17 with sample data is installed.
magento deploy:mode:set developer
As henk-weblead on GitHub mentioned, i don´t know if it is the perfect solution, but for me it´s the ideal solution.
It Works!
Befor i couldn´t acess Adminpanel > Produts > Catalog and Adminpanel > Stores > Configuration
Just remove from table directory_country -
field = country_id, iso2_code, iso3_code
row = AN AN ANT.
(MySql). country id='AN' = Netherlands Antilles.
Have you found another solution? if yes, please let me or let us know all right! Cheers!
