Yesterday it was working fine, nothing has changed on the site. Today I woke up and when I try to download any MP3 or zipped file from the site, instead of downloading the file the page outputs raw content to the screen. That looks like ¯2ñe’Š"$ `qJBâ/R8*„ñK ` û?‚A¤?©lEE¯2ñ¥’¢þ.éy$ƒüQs4¯2ñ¥’‚þ)D „óRŸ£ø*_êÓL8H(†’€"Åÿ2éUoÅW™øRI%þé¹[

I find it troubling because if you check my last question a month ago I believe it was the same script that was not deleting the zip files in the songs folder and now there is this issue. What I would like to know is this something some else has experienced/reported and any proposed fixes?

What I have tried so far:
1. adding a directive in .htaccess for *.mp3 and *.zip
2. changing the readfile($file) to @readfile / file_get_contents() in components/com_muscol/views/file/view.raw.php
3. Turning GZIP on/off
4. Turning Joomla Cache on/off

None of these have worked. Please help.
