Hello Erick,

I am on localhost but look at that thread http://www.joomlathat.com/support/music-collection/general/unset-script-and-css-not-working
why do you load so much css when Joomla is using today LESS and custom css ?

hello Erick,

We just load the default Bootstrap CSS file that comes along with Joomla... if you want to NOT load this file, it's just a line that needs to be removed. You can discuss this over the email if you want.

I have removed the lines in the view.html.php files , it works but it will be more flexible to have all this options in the settings

Thank you
