For some odd reason, it doesn't work for me. It still displays the link for the file's page instead of a player. But the extension is active anyway. Though, my wiki isn't in english. Has this script been tested on non-english wikis?

Apologies that I've only just seen these comments. Github didn't alert me to your posts.

@zoglun - You can configure which Flash player to use with this extension. It should work with the one you name, but let me know if it doesn't.

@maxlefou - I am not aware of any reason this should not work on non-English wikis. Please try the latest version and if you still have issues let me know.

In all cases, please do not respond here, as I may not see it. The latest version of the code and the best places to report any issues can both be found at the extension's project page on MediaWiki.org: https://www.mediawiki.org/wiki/Extension:MP3MediaHandler
