This page lists all the mp3 filenames that cannot be found by the plugin. The typical causes are:

1. The mp3 filename entered in the particular languages gsheet does NOT match the actual filename
2. The file is missing
3. Sometimes the file has been wrongly named .mp3.mp3 or similar

Remember, filenames must be all lower case and contain only alphanumeric characters and _ and – :
english_i_am_going_to_the_hotel.mp3
english i’m_going_to_the_hotel.mp3

The one above it wrong because it contains a space and an ‘ .

For your particular language, please review the errors and change the filename and/or the gsheet filename value so they match.

Note: You will NOT be able to confirm that the change has fixed the problem until the filenames are uploaded to the server and the database synced to the gsheet.
