I would like to post status with adding mp3 file but got message "File extension error."
Why?
and Why I got error messages in English? (my site is ru_RU)
Hello Anastasia,
You need to actually edit the "Files" app at the back end of EasySocial > Applications . After editing the app you will see a settings for "Allowed Extensions". Just add the .mp3 extension and you will be able to upload the mp3 now
