Hello, unfortunately my English is not so good, but I hope you understand me anyway. I installed version 3.1.5 and basically everything works fine. However, I can not upload CSV files. If I go to "Select file", I will not see any CSV files for upload. How can this be? I have searched in the forum and unfortunately found nothing on the Internet.
Best wishes,
Domenik
Also my english is not good!
File browser is an operating system feature (windows, linux, ecc...) , is not a side Abook can manage. Try to select "All file" in file browser window.
