Hello, on our staging site, to save time i exported some products to modify data in the csv file then upload again the modified file, using all same fields etc.
I receive error message ‘Sorry, this file type is not permitted for security reasons.’
Any recommendation what is causing his and how to fix?
The products import export is WooCommerce functionality and our theme doesn’t influence. This error is caused by WordPress security patches that block some file types for security reasons..
