I am trying to upload MP3 files for a site running EE 4.3.8. When I upload via FTP and sync it in file manager I get the following error:

The file type you are attempting to upload is not allowed.

Would appreciate some help on this.


Have you tried uploading it via a file or Asset field, or the file manager?


Looking at this leads me to this file:


which leads me to:


which has a whitelist of mime types the upload class will allow. I do see these lines in the whitelist:

'audio/mpeg', // .mp2, .mp3, .mpga
'audio/mpg', // .mp3

I'm not sure if the file sync is using that whitelist or not (one would assume it is), but check that list and try uploading via the Control Panel and not via S/FTP.

If it is a specific MP3 file and not others, try and make other services recognize the mime type as audio/mpeg or audio/mpg.

  • Here is what my mime.php file looks like: $whitelist = ee()->config->loadFile('mimes'); The rest is empty so I add the following below it: 'audio/mpg', // .mp3 And I still get the error message: Cannot upload file. File not allowed. – forrest Apr 29 '19 at 18:37
