To file can be found here: /plugins/mp3/config.php
When you open the file you will find PHP variables. Below you will find what each variable does when it is changed.
$approve = "1";
// If you want to approve the mp3's being uploaded then set this to 1, if not set it to 0
$mp3size = 5;
// The max upload size of an mp3 in MB.. Note this can't over-ride the php.ini setting.
$mp3max = 5;
// Total mp3's a user is allowed to have
$memberAllow = array
(
'0',
'1',
'3',
'4',
'5',
);
// The memberships ID's that are allowed to upload songs
To over ride this setting add the following in your .htaccess file: php_value upload_max_filesize 15M
In the example above we added 15M but you can of course change this if needed. If this does not work on your server and you have a dedicated server you can modify this setting in your php.ini file.
