Can’t upload some .m4a files, can upload others

Hi,

.m4a files are allowed in WordPress. It’s weird that WordPress is showing that notice for this file too.

I request you to please check again the file format.

Here is the list of files that WordPress support: https://codex.www.ads-software.com/Uploading_Files#About_Uploading_Files_on_Dashboard

If everything is fine and still you are facing the issue.

You can try this plugin: https://www.ads-software.com/plugins/wp-extra-file-types/

I don’t know if it works or not, but give it a chance.

If this method also not works.

Then I think you have to go to add new permitted file types using wp-config.php.

Thanks for the reply, @bizanimesh. Unfortunately, I think I’m going to have to go with changing the ALLOW_UNFILTERED_UPLOADS constant, since, as you stated, WordPress already allows .m4a files. There’s something about this particular file that isn’t totally kosher, and I’ll be darned if I can figure out what it is.
